Define, "too short".

What range are you getting?

What range do you require?

Note that the nRF52840 (only) supports the BLE 5 "Coded PHY" - for range extension ...

Please give a detailed description of how, exactly, you determined that range?

And the test environment?

Zigbee ：#include "nrf_802154.h" in your code, and use  nrf_802154_tx_power_set to set zigbee tx power

Thank you longrain

i follow your code ,i can compile without error. may i know Tx power of Zigbee and BLE the same ?

i see command sd_ble_gap_tx_power_set(); for BLE but i don't know where can i add this command 

When i add this command to my code it's error 

Thank
