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:
Code: Select all
W (16971) esp-modem: Rx Break
E (17023) esp-modem: Frame Error
E (17075) esp-modem: Frame Error
E (17127) esp-modem: Frame Error
W (17179) esp-modem: Rx Break
E (17231) esp-modem: Frame Error
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
Code: Select all
void mld6_tmr(void)
{
struct netif *netif = netif_list;
while (netif != NULL) {
struct mld_group *group = netif_mld6_data(netif);
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
