Sensor density per channel #180

Closed lu4 closed 3 years ago

lu4 commented 3 years ago

I've just noticed that RF24Mesh::begin method accepts channel argument which may mean that the communication channel is fixed not only for a node but for all network. If so then how many nodes can operate on the same channel in close proximity using the RF24Mesh? According to documentation nRF24L01+ module supports Multiceiver Network concept that supports up to six transmitters and one receiver. Does nRF24L01+ module limitations impact the number of clients that RF24Mesh network can support in close (overlapping) proximity. Does RF24Mesh support arbitrary node to node communication. Does RF24Mesh manage channels somehow to overcome the limitation of clients count on the same channel?

About 15-25 tops.

Does RF24Mesh support arbitrary node to node communication.

Yes, it requires nodes to do an address lookup: https://nrf24.github.io/RF24Mesh/classRF24Mesh.html#a38be0ba49fea6986dedd976f18865912 https://nrf24.github.io/RF24Mesh/classRF24Mesh.html#a895f444dcc0cb175faf845c5bdd7a7d0

No, users can run separate RF24Mesh networks on separate channels if more nodes are required.

Got, it thank you!
