How to implement "reapeater/forwarder" in nRF52 ESB?

[Dun Lee]

Hello,
In my case, i'm using some PTX and one PRX. It's working well. Now i want to extend coverage, can i use repeater/forwarder? I tried but have problem with PTX: after send package, it receive only ONE response package, so if this package from repeater then it can't receive other package from PRX.
Why PTX in ESB can't receive more than ONE package from many PRX?

Try to add a counter (or random value) in the packet, this will avoid that the packet is considered a re-transmit instead of an actual new packet.

I tried to test: PTX send package to 2 PRX, each PRX send back one package with different content (include one byte random counter), but PTX only receive one package come first. Event "NRF_ESB_EVENT_RX_RECEIVED" occured only ONE time.

If you want to send data from 1PTX to several PRX, then you must disable acknowledge or each PRX must have a unique address.

My target is how to add "repeater" to system, it will forward message between PTX and PRX. I tried to code repeater change mode TX <-> RX but not ok.

If you use acknowledge you will need to take into account that the PRX may be sending an ACK when you switch from PRX-PTX, this will complicate things.

I suggest to disable auto acknowledge for all data sent in the system.
