Questions regarding on nRF5 mesh SDK

[LeonWu]

Hi team,

My customer is evaluating Nordic mesh solution and below are 2 questions:

1. Do we have any example code for customer regarding on Nordic BLE mesh co-existence with WiFi? If so, any link?

2. Customer may need to use BLE master & BLE mesh by timeslot and BLE master is linked with wearables, but they only find our guideline for BLE slave (GATT) as proxy node. So do we have any suggestion on how they should implement the BLE master/ BLE mesh case?

Thanks!

Hi Leon, 

1. No, I don't think we have any. (we have Bluetooth Mesh and BLE co-existence but I guess it's not related)

2. I don't see any problem. Just modify the co-existence BLE peripheral code to do central and it should be fine. There could be a small issue when the central scan to connect to a peripheral. In this period the mesh performance could be affected (depends on how you configure the scan window and scan interval) but after the connection established I don't see any problem doing Mesh and BLE central.

Thanks Hung, so for BLE mesh co-existence with WiFi, if customer wants to make a router, that is necessary, seems they need to rely on themselves for the solution, right? Do we have any suggestion?

I don't think we have a solution.

Note that BLE mesh requires the radio to be in RX mode most of the time. If you do wifi (which I also assume heavily use the radio) I don't think mesh performance would be good.
