NB-IOT Firmware update on GPY

[hadjidgr]

Good morning to all,

I am currently trying to upload the nb-iot firlware on my gpy. I am using a serial connection and python 3 terminal (the other possibility is to use an sd card). Everything was going well until I encountered an error which is the following! "AT+SMSWBOOT=3,0 Failed!".

I did not put the sim card yet (since I am going to try Orange here in Belgium, i will need a nano sim which i do not have yet).

Picture 1 shows the error on the python 3 terminal and Picture 2 shows the files uploaded onto my gpy prior to firmware install.

I would like to know if any of you managed to get beyond such issue, and also if i may mistaken in what i have done so far.

Thank you to all,
Grégor
