Using 6LowPAN and Bluetooth simultaneously?

[Michael Kreher]

Dear Nordic Team,

I am currently using nRF52840 with nRF5 SDK v16.0.0 for developing a prototype of  wearable device.

The wearable device should be able to act as

a) a BLE peripheral to communicate with a smartphone and furthernore ...

b) as a CoAP / MQTT client / server for sending and receiving data via a 6LowPAN Router to and from the internet

The data transfer via BLE and 6LowPAN can be happen sequentially. It must not be at the same time. But both connections (BLE and 6LowPAN) should be keep open at the same time.

I did not find an example to that and I'am getting trouble when I try to use the IPv6/6LowPAN libs and the BLE libs together in my firmeware.

I found multiprotocol examples for BLE / ZigBee and BLE / Thread but not for BLE / 6LowPAN.

So my question is: Is it possible to implement a multiprotocol solution which uses BLE and 6LowPAN?

Thanks and Regards

Michael

Hi Michael,

I believe it is possible to implement a multiprotocol solution with BLE and 6LowPAN, but we did not continue in this direction at that time. You may find that 6LowPan examples were just experimental tryings, but never have production-level release. This was because Thread protocol appeared. It uses 6LoWPAN and provides more features, so you can find further developments including multiprotocol solutions that are all based on Thread instead of bare 6LowPAN.  Thread multiprotocol examples can be found at https://infocenter.nordicsemi.com/topic/sdk_tz_v4.1.0/thread_multi_examples_dynamic.html.

Best regards,

Charlie

Hi Charlie,

thanks for the quick answer to my question.

I will think about going into the direction of Thread. I will take a closer look on the Thread examples.

Best regards and thanks a lot

Michael
