As i am using Sierra Wireless GSM gps module HL-6528-G2.8V, in which my module is taking gps frames and after filling it in my packet format ,it is sending this packet format on TCP towards server. I am using TCP connect, Packet send, TCP disconnect in this fashion cycle continuous with (...)
I am using a Positioning module that has a SMA port to hot plug an SMA antenna. It also has pins available through its foot print to connect a gps Antenna. The module name is . I was not able to spot a place in its data sheet that describes if both antennas can be connected at once. I want to solder a (...)
I've bought a SIM908C gps+GSM module recently. After some googling I'm confused using this device. As far as I found that this module has pair of Tx & Rx (One for module, One for gps). This is the main confusion to me. Should I connect these two UARTs or just main Tx,Rx will work? (...)
By parsing the required NMEA sentence and extract the required field. connect gps module to PC and capture a few NMEA sentences on Serial Terminal Software and post it here.
if the PIC18 has an internet connection (wired ethernet or WiFi) you can connect to a time server to get the date and time or if you have a modem use that

Hey I am using gps module which can be interfaced directly to microcontroller i have connected the gps module to pc via hyperterminal and i am getting the output with nmea code.. but when i connect the same with uc and i am displaying all the values that are sent from the (...)
Try first to connect modem to PC and test some commands via Terminal program. Than check if your board sends AT commands correctly. Than connect board and modem and try to monitor communication between.
I am posting pictures below of the gps, gsm and max 232 modules. The problem is that the gps reliever has max 232 IC on the board itself, but the output given is in the form of rs 232 port. So, I bought a max 232 board. So, I think I should connect the two using male-male cable. Pls see the pictures and suggest Also, (...)
Can you please suggest a gsm module and gps module for an arduino board?? Cheap and best. Is a MAX232 chip required ? if yes, how to connect??
Hello, I want to connect mention module to MCU but I am not sure what to do with RTC backup supply. In my design it is not important to use this RTC so I want to just to fulfill "minimum requirements" for module to work properly. In datasheet there are 3 options: simple battery, rechargeable battery and super capacitor. Can I use simple (...)
Hello all, I know that SIM908 has not LNA in the gps section. What performance can be expected if I connect a passive ceramic patch antenna directly to the module? Any comments or experiences will be appreciated.

Hello! I purchased SIM5218E with EVB - and have some issues with lua programming Maybe someone can help with giving me hint. I'm able to connect to module via serial port and make a call, send sms, and get gps location via AT command. But when I write hello world LUA script (hello world app example from documentation: (...)
This is a classic problem : ) There are dedicated level converter devices (check, say On Semi, I think they make some). Alternatively most likely if you connect them directly, chances are it will be ok - since the gps module only has an output, and no input. You certainly don't want to connect a 5V output to a 3.3v input, (...)
hi, i am doing a project on a gps controlled vehicle. rite now i am stuck with receiving msg from sim900d module. if i connect sim900d with a pc using hyperterminal all of my AT commands work also when i send a msg a msg echo is produced. but when i send a msg to my sim900d module and try to read it via a microcontroller (...)
Skm53 have logic outputs, so you can connect this module direct to PIC pins: skm53 pins RXD(6) to PIC18F4685 RX pin TXD(5) to PIC18F4685 TX pin RST(4) to any PIC18F4685 free IO pin NC(3) not connected GND(2) ground VCC(1) power supply
If you connect TXD with 5V or GND, I think not damage. If you wrong connect 5V with GND and GND with 5V, this will damage. Did you get any display from that code?
You can connect it via bluetooth.....connect a bluetooth module having ttl interface like this one
Use Bluetooth module withcontroller and use a BT dongle and bluesoleil software to work as a server..... You can set a default passcode and enter the same passcode in the PC to establish the connection..... Instead of a server, you can see the data received by PC on hyperterminal , and capture the logs of the same.............
hi can anyone give me a schematic on how to connect coin cell to rtc pin of gps? should i directly connect it to the gps module pin without any resistor, capacitor etc? thanks
hi all, how to connect skm53 gps module to pic 16f877a?as it is known that the output of gps module output is serial connection at 2.85v ttl ,please anybody help me gps module's data sheet is in this link SKM53.pdf thanxxxxxxxx a lot
its the shield wire of antenna. it should be grounded properly to get the signals.... connect to gps module / board ground...
which ex are you using.... they all come with serial interface, so you could connect it UART of controller directly.. there will be regulator in the zigbee module tos step down voltage, so i think you can give 5v or upto 9v input to xbee module... show us the picture of the module you have... and check for regulator in the (...)
Hi all, i'm trying to send data from a sim508 gsm/gps module through gprs. but sometimes (in 70% of cases), the module can't connect to the gprs network. coz as i test it with PC,after sending "AT+CGATT=1"(attach to GPRS service) for several times, it receives "+CME ERROR: 107"(gprs connection error). does (...)

Just Simply connect TX of gps RCVR to RX of Microcontroller. And for time Tick accuracy connect gps TP to interrupt pin of Microcontroller
Dear all, I have to connect an antenna with a gps module. I placed the antenna very close to the pin (2mm). Do I have to connect it with a microstrip? Problem is the microstrip is wider than the distance between two adjacent pins. Is it true that if the distance is smalller than lambda/10 I don't have to use microstrip? Thx
Hi, Iam on the final year of my PhD. I need to connect a Telit GSM/gps module to a PIC controller. I have a Picaxe AXE210 development board. I need the board to have three sensors connected to it and to transmit via zigbee, until out of range, then it will default to GSM and give gps coordinates. My (...)
