Receiving RDY all the time on BG96

This is my application log. After I send AT+QPING=1,“www.google.com”, sometimes I start getting RDY all the time and my STATUS led start blink, as soon as I have the status led on, I receive a RDY on the uart port. I need help to get a stable connection

Hi phmguizardi,

Please verify your power supply. It reminds us of problems we’ve seen before that the module starts communicating, drawing lots of current which lowers the voltage, and then restarts. Because the power supply could not supply enough current.
You can verify the hardware documents and reference circuit from following link:

Then, change power source, regulator (3A peaks) or decoupling caps.
Cheers !

I’ ve the same issue and the cause is the Antenna.

I can also confirm that the issue is related with current peak demands. This is specially true for GSM/EDGE, where the current peaks required by the module are higher. It is less of a concern for LTE-M and/or NB-IoT.

Regards,
Jose
