Bluetooth Mesh Library Capabilities

The Bluetooth Mesh Library version 1.14.0 has the following Capabilities:

[Library Capabilities]

Net Keys = 3

App Keys = 3

Elements per Node = 5

Models per Element = 11

Subscription per Model = 10

Is it possible to increase these value somehow?

I want for example more than 10 subscriptions per Model.

Hello,

The MESH library is generated according these capabilities.

Any change of these capabilities need a new MESH library generation and then a new version.

Can give some details about the use case ?

Best regards

@EMECH​ We want to know the message source address or an identifier to know from which device the message is received. The STM32_WPAN does not return the source address to the application, so the alternative was that every device gets it own publication address and one device had to subscribe to all this addresses.

Hello,

What about the creation of some groups where each Node can subscribe and publish into ?

If you want to know if the message is received by the target Node, the best is to use MESH reliable message.

Best regards.
