about 1-2 weeks ago, I tried some code on my SARA AFF N211, which compiled completely fine and after uploading the blue onboard LED(s) started to blink.
Now I want to test something else but I can’t get a USB connection… The orange LED turns on only for a short moment and then turns off. In the device-manager I find a new “Unknown USB-Device”, but nothing else.
I’ve tested another board with the same cable and same USB-Port which works fine.
Thank you in advance
Did you try to reset the board manually into bootloader mode?
Connect the board with USB cable to your PC.
Double press the reset button, to go manually into bootloader mode.
You should be able to program the device now.
So first of all, thank you very much @Jan for your help, everything works again.
Now I have another question, is there a way to run my code (which controlls an epaper display) and get information via NB-IoT? Currently I am able to send data from my gateway to the NB-IoT module, but as far as I understand the passthrough sketch, it is only possible to run eiter a NB-IoT passthrough sketch or my own “Arduino” sketch.
I’m glad to hear everything works again.
There can indeed only run one sketch at the time.
You can combine functionality to your display sketch to send the data over NB-IoT.
The N2X library can be used to transmit data for the N211 module.
Hi @Jan ,
Could you provide me an example on how to use the library? I am currently trying to use the library but I don’t know how to use it because it is not well documented. If this could help you, I am using the instructions provided by magenta.
