Out of the box failure

[Ivan]

Dear Nordic,

just got my Thingy:91 out of the box and followed the instruction.

Very surprised that the device could not connect (blue led flashing slowly every 5sec). I'm in Geneva Switzerland about 500m from the next Swisscom 4G antenna.

What should I do now?

This is very unpleasant as the presentation showed something "so easy to evaluate".

Now I guess I have to buy a special SIM card from Swisscom and be only inside the city-center?

Thanks in advance for your support

In order to update modem firmware, I need to buy another tool? Not possible to do it from the USB port?

If this is the only solution then I better ship the device back and ask for refund...

Ok, if you are not able to update, then we have to find another way. You should not have to refund your device.

network is found but no connexion ?

 Yes, the image does indicate that your device does find the network. Difficult to say why it does not connect. I would suggest contacting iBasis and Swisscom. In the meantime, I will investigate the issue and see if I can find a solution.

Kind regards,
Øyvind

Is there no serial bootloader in your chip?

or FOTA ?

or BLE bootloader?

Thanks again for your support

We are constantly working on improving modem updates. Currently, the provided solution is the only method to update the modem FW. 
On the application side, we do have several ways of updating e.g. Updating application firmware on nRF9160 using USB (MCUboot).

That said until we find the solution, we have to try everything. Your device does find the network. Did you contact iBasis and Swisscom (email provided) as instructed?

Kind regards,
Øyvind

Hello Oyvind,

Yes I sent an email to Swisscom M.Bertling) but no reply so far.

I will try update via serial but I need the hex file. Where can I download it?

thanks in advance
