How to set tx power level by app in examples\ble_peripheral\ble_app_uart under sdk17.0.2?

[faithself]

Thanks in advanced. I can create tx power level service, but it just reads current tx power level, I set add_char_params.char_props.write= 1; add_char_params.write_access = SEC_OPEN; but it can't take effect. Would anyone help me?

Hi,

Did you try the sd_ble_gap_tx_power_set api?

Thanks for reply. I've merged a kind of nrf51 framework to implement it. It works.
