nRF24L01+ mesh network

[Arunkumar Dhananjayan]

I am trying to implement a mesh protocol using the nRF24L01+ transceiver.

After reading the product specification, I have concluded that the Enhanced ShockBurst cannot be used to implement a mesh, as the node has to have a fixed role viz. PTX or a PRX. Am I right?

Will I be able to implement a mesh network by disabling the Enchanced ShockBurst and using it in the ShockBurst compatibiltiy mode?

[Arunkumar Dhananjayan]

Yes. I have gone through that thread. I am doing this more for research. So I don't mind if the results don't turn good.

Do you know if the PTX and PRX roles need to be fixed for a node or, if a node can transition between these roles rapidly?

thanks, arun

Yes the roles can be switched on the fly. You will want to study the state transition diagram in the data sheet very carefully, it's very easy to get caught out in the wrong state while doing that sort of switch.

It is also quite power-inefficient to keep the radios in RX mode, but it's no trivial challenge to develop a mesh algorithm that avoid this...
