I’m engineer in mobility rental service development company.
I bought LM5 ( external LTE module based on BG96 — S.korea. M2MNET ).
I have been using BG96 & AWS IOT CORE.
They are communicating through MQTT with SSL.
I recieve QMTSTAT: 0,1 or QMTSTAT: 0,2 error about 2~3 times per day.
I’ve already tried solutions on manual ( BG96_MQTT.pdf )
But none of the solution can’t reconnect to server.
So I use AT+CFUN=1,1 or HW reset ( pull out power and reconnect )
Are there any solutions for this?
Why am I recieving QMTSTAT:0,1 or QMTSTAT: 0,2?
when this error occurs, I checked network status ( AT+QCDS? ) and PDP context ( AT+QIACT? ).
But result was on normal connection. ( Good network signal , Active PDP context )
I want to know actual reason with field examples.
Can I make QMTSTAT errors manually?
I want to test my code with QMTSTAT errors.
