Because the ANT spec defines it as the limit.

In S&F you have two channels. One master channel (channel 1), and one background scanning channel (channel 0). The background scanning channel listens for messages from the other nodes, while the master channels repeats the messages. The master will alternate between the latest messages received from the devices in the device registry.

S&F is already using a dedicated channel to send the updated status, the master channel, channel 1.

Why is there a 24 byte limit on advanced burst?

Hello Petter.

I want to share ALL sensor data on the network with all nodes.

So probably 1024 bytes. I have used this before, just not on nRF.

Just a quick question:

When a node is updating, is it necessary to switch to a "dedicated" channel to update the connected slave? Or can Channel 0 be used to send the updated sensor data?

The S&F uses the standard payload size of ANT, 8 bytes, and not all is used for data. With advanced burst this may be increased to 24 bytes, but that is max.

Could you explain a bit more about what kind of functionality you want? That is not provided by S&F? It is a bit difficult to give recommendations when I don't know what you are trying to achieve here.
