nRF5 SDK for Mesh v5.0.0 support with Amazon echo device

[Ignacio]

Hi

According to Amazon documentation, it is possible to connect a smart home device to Alexa with the Bluetooth Low-Energy (BLE) mesh wireless communication technology.

These are the mesh requirements:

Bluetooth requirements

The Amazon Echo supports the BLE Mesh v1.1 protocol defined by the Bluetooth Special Interest Group (SIG).

For details about BLE Mesh v1.1, see the Bluetooth Specification List and the following specifications:

Mesh Profile 1.0.1

Mesh Model 1.0.1

Mesh Device Properties 1.1

Mesh Configuration Database 1.0

Bluetooth requirements
The Amazon Echo supports the BLE Mesh v1.1 protocol defined by the Bluetooth Special Interest Group (SIG).

Mesh Profile 1.0.1
Mesh Model 1.0.1

https://developer.amazon.com/en-US/docs/alexa/smarthome/bluetooth-support.html

It seems that the nRF5 SDK for Mesh complies with these premises. I have tried running a light switch client from the nRF5 SDK for Mesh v5.0.0 on an nRF52dk but it could not be detected while scanning for devicesc by any of my echo devices (none of them are 1st gen). The device can be detected on the nRF mesh ios app.

I have attached below the RTT logs while running a scan from Alexa environment and also from the nRF mesh app.

Are any of the mesh samples compatible with Amazon Echo devices? If not, how to make them compatible?

Thanks
