Error “Failed to add peer”

Arduino IDE 2.3.4

Sender Board XIAO_ESP32C3

Receiver Board DOIT ESP32 DEVKIT V1

Tested NOW functionality with 10_4_2_receiver multiple boards.ino and ESP32_Sender.ino.

No Problems.

Initially Sender program switches to same channel as receiver but fails to add peer then sender changes to default channel.

Hi Sara thank you for your response.
I have tried the later tutorial “ESP32: ESP-NOW Web Server Sensor Dashboard (ESP-NOW + Wi-Fi)” with the same result.
The Receiver Serial Monitor shows the following:
“Setting as a Wi-Fi Station..
Station IP Address: 192.168.0.236
Wi-Fi Channel: 11”

The Sender Serial Monitor shows:
“Mode: STA
Channel: 11
SSID (13): xxxxxxxxx
Passphrase (10): xxxxxxxx
BSSID set: 0
Failed to add peer”
The results with this version are the same as for the original except the channel remains stable.

Please don’t bother to continue with this as I have decided on a different approach to my project.
Thank you for your time.
