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.

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?
Best Regards
