2 Mbps BLE or 2 Mbps Nordic proprietary mode

[Vlad Mokhnachov]

Hi!

We have working solution with custom rf protocol based on NRF52832 and NRF52840(now it use 2 Mbps Nordic proprietary mode). Now we want improve it.

Could You give some advice about rf mode selection?

As I see 2Mbps BLE mode has better rx sensivity and Co-Channel interference characteristic. But it requires 2 bytes in preamble.

We are using many devices in one room with different rf channels so crosstalk is very important things for us. Will it better use 2Mbps BLE mode?

Hi,

 

In theory you should see somewhat better performance with the 2Mbps BLE mode, but you will have to test it in your specific use case. If building your system from the bottom, not requiring backwards compatibility with the 2Mbps NRF mode you might as well just use the 2 Mbps BLE mode.

 

Best regards,

Andreas
