802.15.4 and Bluetooth client Multiprotocol with nRF5340

[Liam]

Hi,

 4 years ago we implemented a 802.15.4 and Bluetooth Multi protocol project on the nrf52840. Our application continuously ran 802.15.4 and bluetooth was just used for DFU. This has served us very well.

  nrf52840 Bluetooth and 802.15.4 multiprotocol example project 

We are looking to do the same on the nrf5340. I've had an initial look at it and it looks a lot more complicated.

1. Can we do the same thing? Application will runs 802.15.4 all the time and uses BT for DFU?

2. For the nrf5340 we have to use nRFConnect. I think that means I no longer use the nRF SDK for thread and zigbee, the radio-driver and my own 802.15.4 stack which I had to use for the nrf52840.

3. Is there an example I could use for this please? I would prefer to carry on using Segger Studio.

kind regards

Liam

Hi Liam,

1. Can we do the same thing? Application will runs 802.15.4 all the time and uses BT for DFU?

Yes, you can start from Multiprotocol support — nRF Connect SDK 2.0.2 documentation (nordicsemi.com), and it has one example MPSL timeslot — nRF Connect SDK 2.0.2 documentation (nordicsemi.com) supporting nRF5340DK.

Your application sounds very similar to the current Matter implementation. It has OpenThread+BLE support and BLE can be used for commitment and DFU. It could be a good reference for your implementation.

2. For the nrf5340 we have to use nRFConnect. I think that means I no longer use the nRF SDK for thread and zigbee, the radio-driver and my own 802.15.4 stack which I had to use for the nrf52840.

Yes, nRF5 SDK is currently in maintenance state and we encourage using nRF Connect SDK for new development. You can read the blog nRF Connect SDK and nRF5 SDK statement - Blogs - Nordic Blog - Nordic DevZone (nordicsemi.com) to learn more.

3. Is there an example I could use for this please? I would prefer to carry on using Segger Studio.

See the example I mentioned on Q1. To improve the user experience we have created a VS code-based IDE with nRF Connect for VS Code Extension. NCS claim supports SES until version 1.9.2 Installing manually — nRF Connect SDK 1.9.2 documentation (nordicsemi.com). but you are still able to use SES in NCS 2.x.x. SES performance(compiling speed) and UX are not as good as nRF Connect for VS Code - nordicsemi.com.
