Hiya,
We're running a few experiments with a wireless-mesh protocol based on rapid flooding on a few nrf52833 dev kits.
We'd ideally like to use a channel contention mechanism (think RTS/CTS from UART) but we're finding the turn around time of the radio to be too much, even 40 microseconds (fast mode) is too much to reliably contend for a channel. What we'd like to do is to be able to generate a carrier signal without powering up the transmitter and use that as an indication that a device is about to transmit. Any nearby devices would detect the presence of the carrier and initiate their carriers to flood the contention to the rest of the network.
I don't think this is possible even with the 833, but it would be useful if someone could confirm that theory. It would also be great to know if there are any alternative ways of wirelessly contending for the channel in a sub 4 microsecond timeframe.
Thanks in advance.
P.S. your hardware is awesome!
