Activating phy coded and 3 dbm TX power

[Paul M.]

Hello everyone,

I am working on a project where I need maximum range and TX power, since my Bluetooth device will be implanted the signal is strongly attenuated I need maximum output power.
I am having a hard time setting the TX power to the maximum and also setting the phy mode to phy coded. I need this to be in any state, advertising and connection.

I am using the nrf sdk 2.4.0.

How can I do it?

Thanks in advance and best regards,

Paul

Hi,

Can you try to set

For guidance on coded phy check out:

https://docs.nordicsemi.com/bundle/ncs-2.4.4/page/nrf/samples/bluetooth/peripheral_hr_coded/README.html 

When you say implanted, I assume you are aware that 2.4GHz works really poorly in human body since it's mostly of water and thereby absorbed, so the range will be very short.
