Can you set the BLE channel used? #538

Open I-Connect opened 1 year ago

I-Connect commented 1 year ago

I am having some (intermittent) issues connecting to a BLE device. My suspicion is that there is interference with wifi, ZigBee or other BLE devices that I have running here

If a connection fails I retry it 5 times. I am not sure if this is the way to go or that it even works this way but I was thinking if I could change the channel on which I am connecting for the different connection retries maybe this way I could manage it better...

The option to set the channel is listed in the esp idf documentation: image

But I cannot find a way to set the channel in NimBle...?
