ESP-NOW channel switching

Postby ginspe » Mon Aug 04, 2025 7:52 am

I was wondering how does esp-now protocol handle overcrowded channels? Can two ESP devices change channels automatically?

When using the esp-now protocol, you must explicitly specify the WiFi channel.

The two ESP devices must use the same channel.
