BlueNRG-M2SA and long range BLE

Hello,

I am developing a platform with BLE Beacon connectivity and I am looking to extend the range of our device. Until now, I have been using BLUENRG-M2SA module, which is BLE v5.2 ceritifed. I know that BLE v5.1 >= versions include "long range" mode ( 125 or 500 kbps datarate ), usually described as Coded PHY, but couldn't find any mention of it on M2SA documents.

Does BLUENRG-M2SA module support BLE Coded PHY ? If yes, could you point me to a respective document or source file ?

It is often misunderstood that the Long Range Feature (Coded PHY) is not a mandatory part of BLE 5.x, but an option.

BLUENRG-M2SA is a module incl antenna based on the BlueNRG-2, which is compliant with BLE 5.0 but does not yet support Long Range. In the newer SoC BlueNRG-LP, a number of improvements were made, including Long Range (Coded PHY).

Does it answer your question?

Regards

/Peter

One last clarification @Peter BENSCH​ , BLUENRG-M2SA doesn't support Long Range (Coded PHY) for both TX and RX, is that correct ?

Correct, BlueNRG-M2SA does not contain the Long Range (Coded PHY) function, it was only implemented in the more recent BlueNRG-LP.
