Thank you.

I've been having a bit of an issue with receiving an ESP-Now message and then sending a text to my phone. Both work separately, but not together.

Glenn20, thanks it helped. I must read the doc better for the next time...

I just ran a small test... it works (at least for the small test I ran) if you:

Code: Select all

	...
	w0.active(0)
	machine.lightsleep(1000)
	w0.active(1)
	w0.config(channel=chan)
	...

Look at the top of this page maybe it applies to your situation. Thanks, but I do not have a problem with receiver - this part works fine and it is able to receive bigger load then with one sender, but problem is on sending side - only first message after (re)boot is sent. Sending of each other is ...

And I found possible issue with lightsleep. In my sender code: chan = 4 rece = b'\xff\xff\xff\xff\xff\xff' w0 = network.WLAN(network.STA_IF) w0.active(True) w0.config(channel=chan) e = espnow.ESPNow() e.init() e.add_peer(rece, None, chan, network.STA_IF) while True: st = utime.ticks_ms() message = m...

Use a third device connected to AC power as a message broker. (I am working on an espnow proxy to an mqtt broker). I have done it - I have a receiver/sender, which can be managed via HTTP. It is without documentation now, because it is freshly in production state. How to use it is in file src/lib/a...

Hi, I have an update - yes, whole problem was in channels settings - old version did not supported channel change for STA_IF - that means all devices was sending on channel 1. It does not matter what is set in add_peer. And as your latest fix, I can change channel for STA_IF, so when I changed all c...

Thanks for posting this @mhepp63 - I have found some very "interesting" quirks when investigating this issue :roll: Cool! I am happy to see that helped ;) TL/DR : When using AP and STA together, the AP will always change channel to that of the STA (See "Attention" note 3 at https://docs.espressif.c...

Hi, first, I must say big thanks to glenn20... And second... I have a problem with ESPNow and WiFi working together. I need receive messages, handle them and send via wifi, but I am not able to get working code with wifi and espnow together. I have esp32-wroom-32e as a receiver, your latest code (wi...
