For the RM502Q-AE module, I see the following in the release notes for firmware 01.005.01.005:
“Optimized the IMEI anti-tampering function”
Does this change the behavior of AT+EGMR=1,7,“”, or does that command still work as before?
Thank you for the help
Dear @jdub Yes, you can’t use this AT command to modify IMEI.
Thank you @silvia. If you have already used this command to modify IMEI, does the device IMEI simply remain this IMEI value, or does the original device IMEI become the active value once again? I appreciate the help.
Dear @jdub If change IMEI by AT command, this value will be saved after rebot. It is not recommanded to change the IMEI by yourself.
