I am working with Xbee3 module for cellular connectivity.
This module is configured in bypass mode to directly access u-blox sara r4 functionalities.
I am currently running tcp-socket operations to communicate with cloud.
My issue is, after configuring in bypass mode module responds to AT command sometime but sometime it doesn’t reply.
I used below commands ATE0(echo mode control), AT+CFUN=15(reboot), AT+UPMSR=0(power saving mode disabled) etc…
I further found that it happened only when previous network operation wad interrupted by means of either resetting MCU, crashing in between.
So what could be the issue ?
Please let me know if any more information is required from my end.
Any help would be appreciable.
