How to change TX Power of nrf51822

[juli]

Hi guys,

My question is really general: How do I reduce the TX Power of an nrf51822 BLE beacon?

The situation is the following:

1. I ordered this device: https://www.aliexpress.com/item/32917064741.html?spm=a2g0s.9042311.0.0.42f84c4d2j8gPD

2.  I want to track beacons on a room-level basis (based on overall occurrence and RSSI value)

3. The installed readers (Reader1 and Reader2) in the rooms R1, R2 discover the beacon

4. In a worst-case scenario, the reader from room 2 receives a higher RSSI value than the reader from room 1.

My approach would be to reduce the signal strength of the beacon. Is that the right approach? If yes, how can I configure the beacon with the nrfConnect Android App? Do you have other suggestions?

Thanks,

Juli

Hi. 

It's not possible to change the TX-power using the nRF Connect application. 

This needs to be done in the source code of your beacon. 

How to do this is also discussed in several other threads here on DevZone

Ref this function: 
sd_ble_gap_tx_power_set

Best regards,
