I'm trying to refresh
_tcpStatus = sendATreply("AT+CIPSTATUS\r\n", "STATE", 4000);
inside
GSM_MQTT::processing()
after some time TCP connection falls down and AT+CIPSTATUS
responses IP INITIAL
Hi @marcosdepo , Thanks for the update.
@pratikidea, Please confirm whether the issue got solved using these changes.
If somehow gsm signal goes keep alive not reattempting to connect tcp and mqtt. It's stuck in tcpflag true state. Please advice.
