Dear htcompany , May be problem in uart init
Hello. Is it possible to make a Personal Locator Beacon (PLB) Tracker. Can anyone suggest if there any PLB Module (406MHz Transmitter) available which can control via uart AT command? Thanks in advance. Regards.
Don't what "Boot PLUS" is, please clarify. Generally a bootloader must have been programmed to the PIC with regular programmer before to allow uart download. The methods to upload the binary code are different, most bootloaders simply write the hexfile to uart after starting the bootloader via specific command or hardware signal.
Hi I have readymade working electronic product. I am applying reverse engineering on it. The WiFi module is connected to microcontroller via uart( RX & TX). The android app sends command to wifi and microcontroller works as per the command. I have attached a USB to TTL cable on RX and TX also command ground as well of (...)
Hi, you don´t tell wich interface.. But "hyperterminal" sounds like you use RS232 or TTL_uart. --> My hint: baud rate setting, baud rate error, wrong uart setting. Klaus
A straightforward way could be to implement a small soft processor in FPGA and write the AT command handling in C language. Of course it's possible in pure VHDL as well, but no fun particularly. Some necessary steps: - write the RX and TX uart code - write a command state machine to send specific AT commands - write (...)
Hi. Thanks for reply. I am mainly looking for an Embedded Module solution, not a WLAN Router. Is there is suitable Module which can be control via uart AT command for CDMA/GSM to WiFi? Regards. hi, we have desigend the 4G LTE module to wifi. If you want to CDMA/GSM version, just replace the 4G module with CDMA/GS
Hi all. Can anyone suggest if there any uart command Based Stepper Motor Driver Chip/Board? I'll use Bipolar NEMA 17 Geared Motor... 12V/ ~2A. Please advise if any suitable driver available. Thanks.
As far as I know, all mobile phones support "AT" commands. There is no need to separate it from the rest of the phone, even if that was posssbile, just conect it via a serial link, either USB or using a conventional uart, whichever it supports. Brian.
I'm unaware if it exits, but you could alternatively write a very simple routine that waits for ASCII characters from uart and toggle the LED accordingly. This certainly would not exceed too much beyond a dozen lines of code.
Hi All. I am passing very hard time with my Telit Module to activate the GPRS from MCU uart. I know the EasyGPRS AT commands to Activate GPRS and send UDP Data. The strange issue is ... when I an sending the AT command manuallly by typing from PC Hyper-Terminal then all works. Module can send UDP Data to Server. But when I am sending (...)
I'm using PIC18F4550 at 115200 baud rate to get GPS information from SIM908. It works fine with commands sent from PC. Also it works fine with commands from MCU. But the problem is, the MCU can not read the GPS data sent from SIM908. I checked the MCU, it can read data if I send the data from PC uart. But can not read SIM module. It (...)
hello on GSM M95 (QUECTEL ?) after global init : * STAT must be =1 (status of power ON) * NET info must blink GSM must give response when sending "AT" command =>"OK" means uart speed OK send PIN code "1234" ? and test presence of network 20:01:44.125> Test si enregistré sur le reseau (AT+CREG?) // send AT
hello, if i get a right understanding, you want un GSM Simulator program ? I don't know if this kind of software exist.. but you can use a litle PIC as a PIC12F1840 (DIP 8) to write a program wich can simulate a GSM .. handle the uart receive the AT command handle delais for feeback Answer with appropriate message (stored in
Hai, I am work with SIM900 module, and i send AT command with raspberry pi over uart.some commands are working fine but nd then am trying to connect using AT command but the following commands shows the error message AT+CSTT AT+CIICR AT+CIPSTART AT+TIME if am send the (...)
According to the SIMCOM Technical Support: 1) command AT+CMUXSRVPORT is used to make physical uart interface for few virtual ports after AT+CMUX=1 enabled. And for host, there should be some special driver for linux/window OS. 2) command AT+CGPSSWITCH is used to switch NMEA sentence output between USB –NMEA port (after install driver (...)
hi, i am working on stm32f4 and know i try to flash my stm32f4 with uart, but i dont understand about erase command that i found on document number CD00264342, it says data frame command should use two byte addressing as page number to be erased, thanks for any help
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
