FG4619 with Telit GM862 - Auto Baud Rate

Ugur Senturk

Hi. I have a communication problem between FG4619 and GM862 module.

At first run, GM862 has auto baud rate. But FG4619 is set 9600 bps. So, I sent data to module, but there is no answer. How can I solve this problem??

Note: When I set GM862 baud rate at 9600 bps from PC, there is no problem, Everything is good and working.

Thanks...

I've made the same experience with a GE-864 from Telit. Bitrate was sourced from an external 32768Hz quarz.

Outcome: the telit module seems to be very sensitive concerning jitter on the serial data stream. So either set the bitrate to 4800Hz or use another external quarz for bitrate generation.

I'm using 32K crystal too. Ok, i'll try and see it.

Thanks.
