Thanks. MJD093 already helped and explained that the prj.conf had to be changed. Now the setting is correct but the Asset Tracker example still crashes when connection is established... I continue searching for the reason.

Hi,

You can set the network mode as described in the documentation.

This post might help.

Hi Amanda: I already discovered a strange behaviour:

I send AT+CFUN=4 to stop
I send then AT%XSYSTEMMODE=0,1,0,0 to set to NB-IoT
I send then AT+CFUN=0 to save it.

After I reset and restart (AT+CFUN=1), if I send AT%XSYSTEMMODE? I get as answer AT%XSYSTEMMODE=1,0,0,0

This means it doesn't take the NB-IoT mode and that explains why I can't get the connection. After RESET I see the complete flash region as Non-Secure so I would expect we could write it.

How to proceed?

Hi Amanda: post was written mainly by me. However, after I used the ASSET_TRACKER example using SES I never again succeeded to put it to work, even if I change the mode to LTE and back to NB-IoT. Strange is also that I reflashed the latest FW 0.7.029-alpha-update (sorry if not exactly the name) but the software I wrote (printf test message) still runs.

Is the fw you provide like a Softdevice in nRF51? I would expect not! So I wonder why I can't get the unit to factory reset status and then flash your latest FW version to get back to the point where it worked...

Hi Amanda:

Thanks, I succeeded to compile and run it but I can't get any connection to NB-IoT, although I could with original mfwnrf916007029alpha.zip.

Any tips?

Hi,

Download and install version 7-2018-q2-update of the GNU ARM Embedded toolchain to be able to cross-compile for ARM targets.

I tried installing gcc-arm-none-eabi-8-2018-q4-major-win32-sha1 and now it is possible to compile, although it till fails on the creation of the hex file:

1> Post-link command
1> C:\gnuarmemb\bin\arm-none-eabi-objcopy.exe: zephyr.hex 64-bit address 0x4b4fa300008000 out of range for Intel Hex file
1> C:\gnuarmemb\bin\arm-none-eabi-objcopy.exe:zephyr.hex: bad value
Build failed

Any tips?

According to the documentation, this gcc version had a bug and we should use the previous one... which one should we use?

Help is highly appreciated.
