Currently we have developed around 10 to 12 messages as per our project requirement. From past 8 to 9 months things were working fine. Whatever we were developing we get tested it with Tektelic Gateway and Chirpstack Server.
root@ubuntudevimage:/home/devoati# /usr/bin/chirpstack-application-server version
root@ubuntudevimage:/home/devoati# /usr/bin/chirpstack-network-server version
But in the final stage of testing we are facing challenge of "Invalid MIC " type “Uplink_mic” but this error comes in some packets not in every packet. Please guide what can be the issue of this error. The packets that are giving error were working fine earlier.
