When I use the AT+CSMINS (sim inserted status reporting) command on the Ndogo I get a 0, 0 response meaning the SIM card is not inserted which is wrong.
Does it mean my sim card is broken or is there a chance that I have to unlock the sim card somehow?
Yes according to the datasheet, the second value in the response should be 1 if there is a sim inserted.
You could try enabling the detection USR (indicated by the first response value) using AT+CSMINS=1
It might be that in only gives a correct reading if the USR is enabled?
Still nothing, I put the sim card in a mobile phone and it worked fine.
Perhaps someone has a simple Ndogo connection program to test some of its basic functionality?
I tried it with another SIM with the same result.
Is there a way to check if its a hardware error? or could it be caused because the sim needs 5v perhaps? (not sure)
“AT+CSDT=1” switches on the SIM Card detection I found out.
In the reference it says ‘User should select 8-pin SIM card holder to implement SIM card detection function.’
However I cannot find a command for that… The Ndogo has a 6-pin one doesnt it? … meaning its unable to detect simcard?
EDIT:
