Hi, I use sim908 as a gprs module, when I send any command (AT, ATI, ...) to rx of sim908, module echo that command without executing command. (I'd tried ATE0 too) also I updated to B02, B03 and B04 versions and problem still not fixed What's the problem and how can I fix this issue? So many thanks
That's not a Proteus specific problem. The data is received characterwise by the uart. To decode commands you'll usually transfer the data to a circular or linear buffer.
Hi fiends , I have made GSM modul with SIM900d and PIC16F870 . I make voice call and it work only if the gsm number is in code . But i want SIM900 to take number from sim card . I have write number in sim phone book in first position. For this i send via uart AT command : AT+CPBS="SM" ATD>SM1 And this not work ... Could you please he
Consider a simple point. Your uart RX ISR will receive any response send from the modem, including an unkown number of command responses. How can you expect to find a CMGR message text at a specific buffer location? That's the basic problem with your code. There are additional problems like e.g. overflowing the buffer. Instead you should desi
Simple method to transfer data from FPGA with EDK software is uart. Send the output data through Xil_printf command. Create Matlab GUI to construct image from 1D to 2D array.
How will the master microcontroller send data to the second microcontroller(uart/synchronous data transfer)? How will the slave microcontroller(receiving the data) will send the acknowledgement that it has received the data?
Hello : Excuse, I want to take two modules interconnected by the network, such as the following diagram. 108837 I confirm that my setting of baud rate and 8 N 1 are correct and same. How do I set the module? thanks.
@Azzy, Pls use the below said command. AT+CNMI=3,1,2,1,1 You will get the new message indication in your uart...Once this message is captured in the uart just display the same in the LCD...
I have a problem communicating with the M95 via uart. When you send the uart command M95 mi returns the same command that I send. M95 turned on by the pwr key and status pin indicates to me that the M95 is turned on. via FTDI send from PC command "AT" and M95 returns "AT". The uart is used (...)
Hello, I am currently working on a project with GSM module SIM900. I connect this module with Altera DE to send command and read data. I build a Nios system with uart core. Everything is quite good, but I still have a problem. After I power up this module, if I use DE board to send the first command to module, there isn't any response for (...)
i have to configure uart1 on my pic32mx575f256h . so please help me to my problem ? how to configure interrupt based transmit and receive char . and also how to receive full string and transmit full string via uart . suppose i have to send command through PC to PIC like {START} and how to get response like this method . if any c
Hi, I am working on a application where I need two timers with 20kHz and independent duties. I have micro controller on board but it gives me only one timer channel output. Is there some IC exist which can accept some command via I2C or uart and generate two timer outputs? Thanks in Advance for you support; Umesh
hye..I am such problem which i dont know how to insert or apply command GSM module into verilog code.Because we know that uart transmitter and receiver will enable signal be communicated between fpga board and PC. But the problem from me,which I want the signal or message send automatically when vibration sensor be triggered and send to my phone. W
what a pity,my one answers. in fact,when you meet a question,you should search materials from web firstly. if no result,then ask in the forum. - - - Updated - - - i remember the GSM module always has a uart interface. send the necessary command to it.of course,you should study the AT command .
I don't use AVR. I use PIC. If you want help then mention which bit of which register is to be set or cleared to enable uart receive interrupt. I will write a code in mikroC PRO AVR for testing.
Isn't the uart_ command for the internal uart module? If you are using the MAX3100 you need to write your own routine but the example on the Maxim data sheet works fine and if I remember correctly will work on the 16F84A without modification. Brian.
If you want to read in temperature from Android application using BT then you can make a uC board with LM35 or DS18B20 temperature sensor and a BT module interfaced to uC uart pins. You send command from Android application and uC receives it through BT and then sends the temperature reading back in string format. Android app should read in the str
Use uart library in MIKROC to do this task. In help you will find every thing you need.
Ofcourse it will not work. printf will not print to uart .... Incorrect, by default the printf() routine in KEIL is configured to output to the primary serial port, serial port 0. The following document outlines the changes required to move the output to a secondary port, serial port 1, if the de
There is no code which sends or received strings. Is your commands 1 byte wide? Use Serial interrupt to receive data. Also make a function to send strings through uart.
Hi, In any GSM application, uart should be used in interrupt mode, because whenever you apply SMS read command to GSM module, it immediately send SMS message as whole. So you must use uart in interrupt mode. If you want to use uart in polling mode, you should use Hardware flow control. Regards,
Send AT commands using C Code (uart send string).
Hello guys, i'm trying to send input and receive output from a fingeprint device. I have this code. i know how to send the command as you see in below code but i don't know how to receive data from the device. This is what i actually want to do, after sending the command, i need to wait between 1-5 sec because the device will give output at random
HI friends, I am facing one problem communication port of sim908 is connected to xmc controller but sometimes the garbage data is received from uart of controller which is in connection with sim908 i also checked commands , string termination but still i am facing that problem some time . Please if anybody have the idea about how to solve thi
Hello, I will try soon SIM modules, until then cant help you, but in general all works at same principle. You have to use serial communication (RXD, TXD, uart) to communicate with module. Every module has AT command set for communication with module. You have to read some basics articles about modems. I can recommend you one as product of my first
you need to be be more specific of details like what kind of control? what type of motor.. phew.. a whole lot of details.! any way.. you can do somme speed controlling and stuff like that using serial library available with the visual studio tool chain and can send like a command via uart to the uC (assuming) and then drive the motor.
you need use uart and AT command
Hi, I am interfacing controller(MC1322x) with GPRS modem(GL-865). I did the following- 1. Program MCU to send AT command using uart (printf) and receive the response using scanf function. 2. Connect the serial cable from MCU to (Max 232)gprs modem serial port. 3. reset the MCu to send the AT command to GPRS module. But I got no (...)
First of all check whether your Module supports the AT command or not.... If yes you can simply communicate with BT module on serial(uart) with default baudrate.... Also needs to check the power On sequence of the Module
hi, are you using a microcontroller to send the AT commands to the sim900 using uart? you can't transmit 'AT+SVR=svr_val' to the sim900. try transmitting the AT command one character at a time or treat the AT command as a string and simply replace the '?' in 'AT+SVR=?' with the character of your choice. thinking of the AT (...)
Hi, I am interfacing USB Flash drive to my micro controller using VINCULUM device via uart. The Vinculum device sends the response in string format, but in micro controller i am receiving in hex format. i am storing all these hex values in an array. for example if i send IDD command (IDD is for knowing the Device Information), the device w
I'm doing a project in which using PIC24FJ128GA010 mounted on explorer 16 board, using uart n I2C i need to check the battery specifications. I do'v have smart battery command codes. The problem is i wann a program which cofig's uart n I2C so that i can send d codes to batt so that i receive the code description of that (...)

Hai friends, I am using 24Xstream rf module which is connected to the uart port of my pic microcontroller. I've unintentionally changed the configuration of RF module. Now the module is not responding to AT commands. I think I've to restore the default settings of the modem. But the only option, I found is, 1) Using ATRE command (but (...)
For Wireless transmission is it compulsory to use uart Tx Rx ? Just want to know
How can I send the number of steps of stepper motor using uart ? or is there any way to parse the string from uart to int in mikroC
hey all. i have a problem with a uart code i have made in MikroC. i have tryed many things, but cant make it work :I i want to send a text command via the uart and then the Chip lights up some certain leds, but i cant light 2 leds up at once and turn them off as i want to because the loop just keep following its path and i dont know (...)
i didn't get any o/p from the sim900a the module is GSM/GPRS TTL uart MODEM- SIM900A please help me. I used a max232 to connect to pc. In hyperterminal i send the commands. But i failed to get the return back messages. Even to "at
Hye everyone.. it is possible to change the xbee configuration such as adress and id without using computer? what i mean is, just use the microcontroller and send the AT command to xbee via uart..
Between the pics use i2c protocol. One pic master others are slave. Between the master pic and pc use uart (RS232) control. Do you need something like that?
I never do Fbus yet, I do AT command. But, is that Fbus use a uart? If then, you can transmit uart then display any response on LCD. If no response, try to change TX and RX.
Can use AT command. Actually, for first time use, no need to set. You can use default setting to interfacing with uart 9600 baudrate. See this XBee Lesson.
I buy a Bluetoth I know that this device connect to the micro controller with serial communication in uart protocol but i don't understand how I connect the Bluetooth with the micro controller?
"i can't find any specific command to do this" AT+CIPSEND is a command specific sending tcp data through gprs. "how i could send this" Just like you send the command. Write these http commands to uart of your module.
We are using a microcontroller to provide IO (ADC and GPIO) to control and measure external devices. I have successfully programmed uart functions of microcontroller device (Silabs C8051F380) to communicated with host programs on PC over RS232 (COM1) interface. For this project the host sends a command to the device in which the device returns a re
GSM and GPS are based on serial communication through uart. memory chips are usually supported by I2C protocol.. what explanation you need....
have you tried looking at the signals with an oscilloscope, e.g. write out to the uart "AT\n\r" in a loop 1. You should see the 3.3V from the uart then 5V into the modem 2. if that works you should the modem reply at 5V then 3.3 V into the uart this should show where it is failing (could the baudrate be incorrect?) a MAX3232 sounds a (...)
Hi all, I am new to mikroC, I need some help for my project...... My project is to read a text file from a sd card and send it via uart through pic.... I have completed the project in mikroC, and the pic is able to read each byte from the file and send it via uart... by using the command Mmc_Fat_Read()... But the problem is , for (...)
