Re: BLE Controller Core Spec 5.2 Power Control Feature
Chettimada, Vinayak Kariappa
Currently the link layer is undergoing a major overhaul of the control procedure design. You can refer to the changes in the topic-ble-llcp branch.
That said, you are welcome to send a draft PR with your implementation, reviewers will guide you towards contributions that can be reused towards the new design.
You can start by involving reviewers early by sending in draft PRs.

Subject: [Zephyr-devel] BLE Controller Core Spec 5.2 Power Control Feature
I am working on the LE power control feature of Core Spec 5.2. I am almost 60-70% done defining the air-messages and the state machine within the llcp and he actions/behavior upon receiving PWR_CTRL_REQ/RSP or a related REJ. Also, not currently handling PWR_CTRL_IND and this should come later I guess. Feature still untested but it is in the pipeline.
Main issues now are:
2) Insuring there are no leaks or any PWR_CTRL received pdu not released
3) Issuing command to change PHY TX power (I used the same method as in the host based TX power that this PR https://github.com/zephyrproject-rtos/zephyr/pull/19779 is addressing which seems to only change the connection TX power in the connection record and I guess the radio manager will then somehow use that to control the PHY?)
4) Overall testing. I need help here from the Zephyr Bluetooth developers.
Since this is my first potential contribution to Zephyr, I am following the contribution guidelines by posting in the mailing list to discuss the feature before proceeding with a pull request.
