Our rm502q 5g module is not able to detect sim. what can be the possible reson for that and solution.
Dear @Anand
Did you try with another device? Or test with another SIM card?
Please query AT+CPIN? AT+QSIMSTAT?
Yes, I tried both but I am getting the same responce. plz provide some solution. our team has been waiting for days from your side reply.
Check with AT+QSIMDET?
Please do not use pictures when you need to show text.
AT+QSIMDET?
+QSIMDET: 1,0
OK
Then switch it off with AT+QSIMDET=0 and see if that helps.
tried this, not working
AT+QSIMDET=0
ERROR
Check the syntax then, AT+QSIMDET=?
It probably expects 2 parameters even for disable action, so the command to try is AT+QSIMDET=0,0
Dear @Anand
From the response, it shows the SIM didn’t be inserted.
Did you change SIM card to another slot?
AT+QSIMDET=0,0
OK
This is the responce I am getting.
Dear @silvia
Yes, I did tried this with different SIM card but the module is not detecting SIM at all. when I am changing SIM slot Its not changing as given below.
AT+QUIMSLOT?
+QUIMSLOT: 1
OK
AT+QUIMSLOT=2
OK
AT+QUIMSLOT?
+QUIMSLOT: 1
OK
I have connected 5g mod (rm502q) to a respberry pi (cm4) and executing these commands. Can there be any possibilities of error in that?
Dear @silvia
Can you Please provide me with latest firmware and procedure to update via Respberry pi.
