I use the SIM800L GSM unit and tried it with the flowcode GSM_Test.fcfx as given in the wiki GSM page
https://www.matrixtsl.com/wikiv7/index. ... (Wireless).

It does not work and gives an init fail 69.

This can be probably due to the fact that my SIM card is protected with a pin code (pin number). I bought a new SIM card, but it comes with a pin code. I can not delete it, but I changed it into 0000.

Can someone helps me to manage the flowcode to include this pin code (pin number)?

With kind regards

I found a solution. I delete the pin code from my SIM card, using a cell phone. And now it works.

Kind regards

Hi

Just wanted to let everyone for future reference know you can enter the pin with "AT+CPIN" command.

Take great care to not lock your card with too many wrong attempts, or atleast have the PUK at hand...
