Hi!
I use a ftdi adapter to connect the fona 3g and the raspberry pi. I use pyserial to send AT command, if i use a baudrate above 115200 i don't get any answer from the module. How do you manage baudrate above 115200 ?
Best regards

Re: FONA 3G baudrate
115200 is the maximum auto-baud rate. You have to use AT commands to set a higher baudrate. Check the datasheet for instructions on how to do it.

Re: FONA 3G baudrate
When i change the baud with the command AT+IPR=XXX i don't get any answer from the module if XXX > 115200 :(

Re: FONA 3G baudrate
You first need to connect to the module with a maximum budrate of 115200. After that you enter the command AT+IPR=XXXX after that you need to send AT&W to store the baudrate (in case of powerloss) and close and re-open the connection with the new baudrate. The baudrate should pe suported by the GSM modem, USB 2 serial converter or any other device.
