Apache-Mynewt/Zephyr mesh receiving a String

[Adityaxavier]

Am currently using Apache Mynewt.

BLE Mesh works great when utilising the provided samples.

However, because of lack of documentation / my lack of knowledge am unable to figure out how to implement Server to receive a String over BLE MESH.

What are BT_MESH_MODEL_OP_2 used for and where would I find more documentation about their need / use.

Incase we change / add another service apart from on/off, would we need to implement the same on Bluez 5.47 meshctl in order to use it from linux side?

Hello Adityaxavier,

You will be better served asking MyNewt/Zephyr related questions in their respective communities, both of which are very active and provide excellent support...

Hope this helps,

Hello Adityaxavier,

In Bluetooth Mesh, there are certain models that are mandatory and are included in so-called Foundation Models. These include Configuration Server & Health Server. Config/Health Client(s) are Foundation models but are optional.

Additionally, there are standard/generic models Generic-xxx, such as GenericOnOff etc. which provide template actions/responses to standard devices, as well as models for sensors, lighting etc. These are all documented in the Bluetooth SIG Mesh Model specification (not to be confused with the Mesh Profile specification which provides insight into the internal communications and message handling of a Bluetooth SIG Mesh stack).

Finally, in the Nordic and Zephyr (as well as other) implementations of Bluetooth Mesh, it is possible to implement custom/vendor models in order to bring specialized functionality to the fore. The following link provides details of Nordics specific handling of that process. By following the Mesh specification, interoperability across implementations should exist even for custom/vendor models.

This concept of custom models is further demonstrated within the Nordic Mesh SDK via the Simple OnOff custom model and (as it alludes to) should not be confused with the GenericOnOff SIG model.

Please let us know, should you require any additional insight.

regards,

Actually, the question was more towards technical feasibility. From what I understand in BLE Mesh, we have to stick to one of the listed models.

Implementing a custom model would require changing core mesh implementation. Is this even possible in nRF SDK ?

I'm not too familiar with Apache Mynewt, but the nRF5 SDK for Mesh documentation describes how you can create new models, see this.
