Arduino GSM Shield R3 not working 2022? Read this!

Official Hardware Retired GSM Shield

Hi,

Its been a few years since ive used the GSM shield, however it no longer works. But after days of searching & testing, the current IDE (2.0.0) is the one to blame.

  • if your modem is not working
  • if your IMEI is 0
  • if you shield stops working or hangs
  • if modem = ERROR, no answer
  • if script (examples) not working

USE IDE 1.6.5!

I hope this helps anyone in 2022 or later!!

Thx to rfh
