PA/LNA switching with softdevice (sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &options)) doesn't work with P1.* pins


I didn't manage to run PA/LNA switching with softdevice (function: sd_ble_opt_set(BLE_COMMON_OPT_PA_LNA, &options)) with P1.* GPIO pins.

Note that all P0.* pins are working normally, especially the LED pins P0.13 - P0.16 are normally working.

I tried all the combinations of 2 PPI channels and a GPIOTE channel, it didn't work for P1.* pins.

I have NRF development board PCA100056, version 0.9.3, S140 SDK version 14.2

I used the code suggested in the following posts:

Forgot to mention that the function sd_ble_opt_set() returns error with code = 7.

Thank you for consideration!

Best regards,
