Hi all,
I was trying to integrate the quectel

connection in the ofono driver. I used AT+QIOPEN for opening the
socket, AT+QIRD for receiving data from the server and AT+QISENDEX for
sending data to the server.
Out of curiosity, why? Since you're running oFono, which runs on Linux,
you should have a fully-featured and much easier to use IP stack
available to you?
The 3 functions are working correctly if I executed it directly in the
serial port. I had issue with ofono when it send the AT+QISENDEX. Below
is the command:
char const *command2 = "AT+QISENDEX=2,\"48656c6c6f\"";
g_at_chat_send(data->aux, command2, none_prefix, NULL, NULL,NULL);
The first execution of the QISENDEX works. My server received the data
but when I try it again, the ofono stuck somewhere where the it couldn't
run any AT commands anymore. Then, I killed the ofono and opened the
serial, I ran this command AT+QISENDEX=2,"48656c6c6f" and it works fine.
You may want to enable AT command debugging. See HACKING for details.
One possibility is that the firmware gets AT command response formatting
wrong. E.g. something in the response confuses GAtSyntax.
