Re: increasing nRF52 Bluetooth range

Hi Vikrant,

 

The Zephyr BLE controller does not implement the Tx power set interface in the upstream code, hence Zephyr controller operates with +0dBm transmit power.

Feel free to supply the correct h/w Tx Power enumeration to callers of https://github.com/zephyrproject-rtos/zephyr/blob/master/subsys/bluetooth/controller/hal/nrf5/radio/radio.c#L112

 

nRF52840 supports +8dBm and Zephyr controller supports external power amplifiers too using the PA/LNA GPIO lines, in case you want your h/w design to have external chips to get further tx power.

 

Regards,

Vinayak

Subject: [Zephyr-users] increasing nRF52 Bluetooth range

 

Hello,

Recently while doing demo test in my office, I found that

range of silicon labs SoC with max. +10dbm power = 2 * range of nRF52 with max. +8 dbm power

Silicon labs demo kit was executing own stack.

 

Is this because of only +2dbm difference ?

How to increase nRF52 range by configuring Zephyr ?

Thank You !!
