ESP-IDF and BG96 GSM Module
Posted: Thu May 16, 2019 3:20 pm
Hi,
i'm trying to use Quectel BG96 GSM module connected to my ESP32 (using WROOVER for ESP32 and the Quectel demo board).
I've tried the example and works fine; my software as well is working fine but i'm facing problems when i try some test:
1) if i try to disconnect the serial connection i read within the log:
but no "events" arrived
2) When i try to deinit both DTE and DCE, it seems to work but after a couple of seconds i receive an error, most of the time in
In the last line netif is null!!
It seems like pppos has not been disconnected completed to lwip.
3) In order to understand if GSM is registered with good signal, do i have to pull signal strength? Is there any callback about that?
Do you have any idea?
Thanks in advanced for your kindly help
