I wonder if there is anything here that might help you https://github.com/Seeed-Studio/WioLTE_Cat_NB1_Arduino_Library/pull/6
@dsghi That is a good bug that someone caught ... but I'm not using that library. I'm attempting to use this "Breakout-Massive" library.
I've also been testing directly by using a "passthrough" app to talk directly to the uBlox modem using M-Center (the uBlox debug application) and can't get it to connect at that low of a level.
It's weird that no matter what I do, T-Mobile seems to be rejecting the registration request.
BUT ... I can put these same SIMs into my Quectel EC25-A based LoRa gateway, and they connect and register just fine.
Maybe T-Mobile has decided the uBlox modem is not an approved device?
Well ... I'm not sure if this is true ... but it seems that the SIMs that I bought through the Twilio Programmable Wireless Console are NOT compatible with this board or usage?
Someone told me that I am supposed to request the Beta Narrowband SIMs?
Oh yes that'd be it, the regular Sims or super Sims are not compatible with Narrow Band. If you're going to Signal next week, you can probably find one there. That's where they originally handed out the Alpha kits.
@Humancell @dsghi is correct - the SIMs that are shipping self-service today are not Narrowband capable. We will have SIMs to give away at SIGNAL this coming week but we can also get some SIMs sent out to you. Please open a support ticket here and reference this github issue and we'll get you some Narrowband SIMs to work with: https://support.twilio.com/hc/en-us/requests/new
Hello,
Thanks! I've opened a ticket (1987555), or added to the ticket that I had open. I look forward to getting some SIMs, and getting a chance to test this!
Curious ... any additional steps that I need to follow to get some NB-IoT SIMs?
Hi @Humancell - sorry for the delay, let me respond to you 1:1 on that ticket momentarily.
I've submitted a ticket to Twilio on this already, but wanted to make sure that you were aware of this also. Prior to using this library, I had written my own "passthrough" application (similar to your Passthrough.ino) so that I could test with m-center to see what is going on.
I've got two SIMs that work fine in a Quectel EC25-A with Programmable Wireless. If I put either of these SIMs into the Seeed board that I have (https://www.seeedstudio.com/Wio-LTE-Cat-M1-NB1-p-3055.html) I continue to get a "register denied" response. I'm stumped on what it might be.
I was hoping that your new library might educate me about some uBlox configuration AT command I was missing ... as I had resorted to writing my own simple library. But even from M-Center, no matter what I do, I can not get the uBlox to connect to T-Mobile here in my area.
The response to the +COPS=? query:
+COPS: (1,"Twilio","Twilio","310260",9),(1,"310 410","310 410","310410",9),,(0,1,2,3,4),(0,1,2)
So it is seeing T-Mobile (310260) and what is interesting is it even returns the "Twilio" name. But then the +CREG command returns the registration denied (3):
AT+CREG?
+CREG: 2,3
As you can see below, I can't get this new library/sample to work either.
Thoughts?
