I have a Linkwave pilot hat with an HL8518 module that has been working fine for several months. But two weeks ago it started to fail at startup: the module resets as soon a I enter the PIN (at + cpin = “xxxx”).
And it only happens with an Orange SIM. When I put a SIM from another company (for example, Movistar) it works fine.
Just in case it was a hardware problem on the SIM card, I bought a new one. But I still have the same problem.
Any clues to what’s going on?
Thank you
Hi @chema,
Maybe you can provide a bit more details to help understand the situation:
- Which firmware are you working on? If it is not the latest. Please upgrade it and try again on Orange SIM.

- Please check APN and band on the module and verify the proper values are input
Check Band:
AT*PSRDBS?
Set to all bands or band which is supported for Orange
AT*PSRDBS=<mode>,<band>
<Mode>
0 Set <band> at next switch on
1 Set immediately
<band> Bit field type parameter; to set several bands, sum up the values
1 GSM 850
2 GSM 900
4 E-GSM
8 DCS 1800
16 PCS 1900
32 UMTS_BAND_I
64 UMTS_BAND_II
128 UMTS_BAND_V
256 UMTS_BAND_VI
512 UMTS_BAND_VIII
1024 UMTS_BAND_XIX
GSM 900 is included into E-GSM band, so the module answers 2045 to “AT*PSRDBS?” when all bands are selected.
Check your APN
at+cgdcont?
Set APN if it is not ready
at+cgdcont=1,“IP”,“your-APN”
Please feel free share any concern and tick “Solution” if your question is answered
Thanks
