LTE-NB config for Swisscom
-
Has anyone ever used the NB from Swisscom?
I'm having trouble attaching to their network.
I'm using band and apn in the attach settings. Is there any extra configuration needed? -
@GRIS What version of the module hardware and firmware and modem firmware are you using? What band do they use?
-
Hi @jcaron, Swisscom uses band 20.
Hardware info:
Fipy v1.0r and also v1.2;
release='1.18.2.r7', version='v1.8.6-849-df9f237
NB1-41019 -
Has no one ever tried Pycom boards with Swisscom LTE-NB??
Any help would be appreciated since swisscom conctact can't figure out the problem either... -
@GRIS Maybe you can try downgrade your f/w - details below:
@Edward-Dimmack said in OSError: Couldn't connect to Modem!:
@rskoniec Thank you for that. I tried all the modem firmware and it seemed to have little effect. However, I changed the firmware version to version 1.18.2 on the FiPy and so far they are all working. Even the ones that weren't working at all. Not sure if it will work for anyone else and I haven't done thorough testing yet. Will update if anything changes.

Some extra info:
On the attach command no errors are raised, it just simply never attaches.
With the same devices, we connected to Altice Portugal NB network with no problems (exactly the same code, hw, firmware versions, etc...)
