Re: increasing nRF52 Bluetooth range
Chettimada, Vinayak Kariappa
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.

Subject: [Zephyr-users] increasing nRF52 Bluetooth range
Recently while doing demo test in my office, I found that
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 !!
