Hi,
Have one of these Sim800L Coreboards working fine and ordered another board recently.
However when the new board is powered up, the netlight flashes as if its searching, eg about once per second for 13 times, then pauses for 3 seconds then resumes for 13 flashes again etc.
I can talk to it with AT commands ok, but AT+CSQ, signal strength, shows 0,0 instead of 30,0
Cannot find any reference to this sequence of flashing , though not sure why it stops searching after 13 flashes ? the other board can take 20 flashes before it connects ok.
Does anyone know if these 13 flashes are a known message or just got a bad board ?
thanks
