I am using the Sixfab core with the Quectel EC25 module.
I am using a SIM card, however, i can’t connect to any network or even scan any network:
+CME ERROR: 3
Note: i don’t have an external antenna connected, is it needed?
Make sure your antenna is connected properly.
So, it will not work without the antenna?
Yes, it won’t work without an antenna.
Oh thank you so much, i did not buy the external Antenna initially, already ordered it!
I already have my antenna connected but the module still shows +CSQ: 99,99, and won’t do anything.
