Hi
I am playing around with ble_app_uart example from SDK, it works perfectly fine together with ble_app_uart_c. Now I want to modify it so that it would work in long range mode (or coded PHY). I tried adding these two lines to advertising_init function:

init.config.ble_adv_primary_phy = BLE_GAP_PHY_CODED;
init.config.ble_adv_secondary_phy = BLE_GAP_PHY_CODED;
XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
init.config.ble_adv_primary_phy = BLE_GAP_PHY_CODED; init.config.ble_adv_secondary_phy = BLE_GAP_PHY_CODED;
After doing that, the application crashes in function advertising_start, because the function ble_advertising_start returns 7 (I believe this is the parameter error). But the hard part is now how to know which parameter is wrong if there are so many... Does anybody have an idea?
Here is the code from my main.c for reference (I haven't modified anything else):
