Q2686 based Gateway design

[chethankp]

Hi,
I have designed my own Gateway board using Q2686 wavecom module.
but its not working .. I have attached the schs of my design pls review it.
Tested:
1.We are getting the internal voltages i.e 1.8v at pin 5 and 2.9v at pin 10 of q2686 module .
2.We have provided 3.3v directly to the ON/OFF pin module.
3. We tested all Vbat voltages pins, we are getting all the voltages .
4. The same q2686 module works fine on other board.
problems.
1.Sim in not detecting (this we tried by putting the preprogrammed module for SMS services )
2.We are not getting the clock at the SIMclk.
3. UART1 : Debugg is also not working ,not taking any at commands (its not getting synchronized with the Serial terminal, nothing is coming on serial port when connect and restart).

Send your requires features. I will guide you for development.

Hi,
I need to acquire 12kb of data from serial port and upload that data to the server.. and need send the status of the data send etc.

thanks

Check your OS version inside the Q2686. Down load the OPEN AT environment. There are too many API availabe. You can easily send the data to ant server.
First you chose the transmission protocall.

Since u mentioned that it is worlking in other board,,
can you please chk the reset mechanism is happenning properly...
Is basic AT commmands working???

also is data transferred using hardware flow control try use only three wires Tx,Rx,gnd,

how much Q2686 costed for you...

have wriiten a code On Q2686 to receive the data from serial port (UART2) and upload to the remote server through GPRS uing both TCP and FTP to upload the data, I'm using the sample application present in the open AT to do this .
Info:
Baudrate:9600
Open AT OS:6.20.04

I'm trying to upload 12kb of data to server But I'm facing lots of problem
Problem When I tried With TCP: I sent the data from PC using hyper terminal to the wavecom module(q2686) via UART2(Here I have used level convertor IC to B/W PC and wavecom module),
It uploads the data fine when I sent a ".txt" files from the PC but It didnt upload correct data when I sent ".dat files" I tried this many times same problem exits with ".dat" files but there is no problem when I tried to upload ".txt files it uploads all12kb of data . and it was uploaded only 2 to 3 kb and also it was not correct data , why its happening like this ".dat" files.

Problem When I tried With FTP: Here it uploads first 6kb of data fine and for the next 6kb it duplicates the same first 6Kb of data. ie out of 12kb first ~6 kb data is correct and next ~6kb of data is just duplicate of previous 6kb of data.

Here I have attched the function moudule(UART part and data upload part) which I have written for TCP part . and for FTP I retained the same UART part and changed only the uplaod part (used ftp sample program) .
