ESP-NOW throughput drops with nearby devices

[prem111as]

Sorry for going a bit off-topic, but I’m sure there are people here who know ESP-NOW on the ESP32. I know that in unicast mode we can’t reduce the number of retransmissions, and I suspect those retransmissions are causing the problem.
I’m sending about 30 packets per second between a TX–RX device pair over ESP-NOW in unicast mode, with each packet being 3000 bytes (I fragment it into 2 parts). That gives a throughput of around 35 KB/s.
The problem is that when I have multiple such TX–RX pairs nearby on the same channel, it’s enough to turn off just one pair, and all the others drop their transfer rate almost to zero. The same thing happens when I bring a Bluetooth device close — it interferes with all our ESP-NOW pairs.
I should also add that the ESP-NOW channel on the RX is the same as the AP channel we create on the RX (it obviously has to be the same).
Are there any ways to prevent this?

Hey !
IN this phrase : "I should also add that the ESP-NOW channel on the RX is the same as the AP channel we create on the RX (it obviously has to be the same)." did you mean that it needs to be the same as the AP channel we create on TX instead of RX?

So shouldn't you set the other pairs on another channel ?
