nRF52832 WLCSP Radio problem

We build our own board with nRF52832 and have problem with radio. nrf52 Schema

We start with sdk12 ble_hid_keyboard project. I disabled scheduler ,start advertisement and toggle 2 IOs(P0.26,P0.25) on the main loop without power manage, the result is that we cannot see ble device when we scan for it with phone and spectrum analyzer.

If i toggle other IO (P0.27,P0.29) ,there is no problems to detect and connect to ble device.

main.c

Any suggestion?
