Multiprotocol Radio - priority of protocol

[PiotrP]

Hello,

I am evaluating multiprotocol radio with BLE and OpenThread using NCS 2.0.2. I know that in documentation it is said that BLE has priority over 802.15.4 radio. But is there any possibility to change it? Or to switch priority to Thread protocol?

Hi PiotrP,

I take it that you have read our documentation on Multiprotocol Support. The motivation behind giving BLE the highest priority is:

In this solution, Bluetooth Low Energy has always priority over 802.15.4 protocols. Because of the nature of the Bluetooth Low Energy protocol (TDMA), the Bluetooth packet error rate should be 0% in absence of any external interference.

As such, it is not possible to give Thread or any other 802.15.4 protocols priority over BLE.

May I ask what the reason for this interest is?

It was simply our company internal question - if there is any possibility to maintain prioritization on the radio level. I am totally aware of nature of BLE and Thread networks.

I am afraid there is no possibility for that right now.

If your company has a strong reason to request such feature, I would be happy to relay that information to our internal (but your local Nordic sales representative would be the preferred and better channel for that)
