Hi,
during the development with the bg96 we encountered a problem, which we cannot explain to ourselves.
Basic configuration:
BG96
software version BG96MAR02A07M1G_01.014.01.014
Vodafon Simcard
Problem 1:
After some time the BG96 can no longer publish to the azure cloud. The time could be 2min or sometimes 30min. We get the feedback +QMTPUB: 1,28,2. We get no message that a connection has been closed. Only a restart of the module can help.
Problem 2: To solve problem 1 I wanted to do a disconnect/close. But after a disconnect we don’t get a urc “+QMTDISC: 1,0”. Only when I restart the module with AT+CFUN=1,1 we get a +QMTDISC: 1,0. We get then on the following “close! as well as each further command, without having received a urc from disconnect, always a “error” feedback.
