nRF5340 U-Blox Nora B120 FEM module

[.....]

Hello,


I have U-Blox Nora B120 dev boards. Nora B120 chip has built in Skyworks SKY66405-11 FEM IC and I want to use it.

I read in the documentation to copy folder with board to SDK folder. I did that, but my program didn't compile.

Regarding to image above (which is a screenshot from the documentation): I copied ubx_evknorab12_nrf5340  - NOT ubx_evknorab10_nrf534 as in the picture above (nora B10 does not have built-in FEM)


Then I read to modify nrf5340dk folder. I did it and my program compiled. (screenshots from the documentation below)



Documentation links:
EVK-NORA-B1 User Guide
NORA-B1 series, system integration manual



But there is a problem.
My program is a combination of modified "ble-timesync-demo" and "Multi-NUS Central" / "Peripheral UART" programs.
LINKS:
https://github.com/nordic-auko/nRF5-ble-timesync-demo
https://github.com/NordicMatt/multi-NUS

This program has been divided into 2 separate programs. One is the MASTER - data receiver which sends the synchronization and second one is the PERIPHERAL - data transmitter which receives the synchronization.

With "normal" 5340dk configuration it works properly, but on modified 5340 board config - MASTER is receiving data and sending synchronization, but PERIPHERAL isn't receiving synchronization data.


Can you help me resolve this problem?

PS: For now I am using SDK v2.5.0. but I plan to upgrade to v2.8.0 or newer. Will the configuration changes needed to run FEM on Nora B120 in SDK v2.5.0 be the same as in v2.8.0 and v2.9.1?

Hello,

I think perhaps U-blox will be able to provide the best support here... I will try to help, but you might want to start conversation with them as well.

I checked the NORA-B1 EVK product page, and it seems that the "System Integration Manual" document you linked isn't listed.
How did you arrive at that file? I find it quite strange that a guide involving modifying the nrf5340dk_nrf5340 target is in use when dedicated board file is already available. 

I think we should try to stick with the dedicated board file for now and start with some simple application first.
Could you please try the beacon sample in zephyr/samples/bluetooth/beacon?

Best regards,

Hieu

Hello,

Bluetooth beacon sample doesn't compile on ubx_evknorab12_nrf5340_cpuapp. (on nrf5340dk_nrf5340_cpuapp it compiles).

Hello,

Looks like there are some API change between NCS v2.5.0 and v2.6.0, and the u-Blox board files are not compatible with v2.5.0.

Could you please retry with NCS v2.6.0? I looked into the fix and think that it would be simpler for you to change SDK version instead.

Best regards,

Hieu
