Hello,
I’m evaluating the new BG77 (firmware BG77LAR02A02) and have run into an issue. I am unable to get my IMEI number. Both CGSN and GSN fail with a “Memory Failure”. The AT+CIMI and AT+QCCID commands both respond with correct responses and it happily registers on the network.
AT+CGSN
+CME ERROR: memory failure
AT+GSN
+CME ERROR: memory failure
Anyone have any thoughts?
Thank you.
Dear lucashozen ，
I re tested it in my side ,
This cmd work fine , I attached the AT log as below , Maybe , Due to your BG77 module is ES sample , Maybe the fab has not burned IMEI .
If This IMEI really important to you , Pls send email to support@quectel.com , we will sent the IMEI burning tools to you , thanks
