Hello,

I have two GSM modules and one of them seemed to be faulty: the board' D4 ERR led  (SGM module, 5.98) always ON since first switch on?. What can I need to check ?

The other GSM module is working fine.

Thanks

Could it be a nework error? Have you tried exchanging the SIM cards between the two modules?
Also please check the antenna connection, and the ID settings

Some SIM cards are code-protected (ie. need to key in password to use them).  You need to disable the feature if that is the case.  ;)

It's alright now. I have no answers why it' s OK now. Actually I did not change any on board ID, sim card, antenna... just after several full downloads for other responses' changes.

Thanks
