nRF52840-DK ble_app_hrs setup for Long Range and 8dBm

Hi,

For this evaluation stage of the nRF52840, I would just need to make a fieldtest the range distance I can get with 8dBm in the nRF52840-DK and a smartphone running the nRFConnect or better the nRFToolobox Android apps. Of course, the final result would be dependant of the smartphone, but I need first to fix the nRF52840 parameters without havign to rewritten any code, I thought on the ble_app_hrs because I see some other ticket where it look that it was possible to program the nRF52840-DK TX Power to 0, 4 or 8dBm. But I have no clear idea of how to do it?

Please, could you suggest any other option to make this fieldtest? If the result could be enough for the application, ee would decide to use a module with the nRF52840.

Thank you.

Hi,

I have found this case

https://devzone.nordicsemi.com/f/nordic-q-a/54562/location-to-set-tx-power-in-advertisement-and-connection-mode-also-change-them-dynamically-at-runtime/220720#220720

Following this case I have found in the ble_app_proximity is a way to setup de Tx_Power as a part of the advertising_start() process. I have tested according to it using the tx_power_set() function into the main.c file and defining the TX_POWER_LEVEL at the begginning of this file. I have testes using the nRFConnect RSSI measurement and it looks that it works.

Best Regards,

Joel
