Can't compile for m5stack atom lite bt proxy

[dixonbg]

Hi there,

I've recently bought a Wizmote, thinking I can link it with the Wiz integration. Now that I know it broadcast some ESPNOW packets, I thought that my tiny Bluetooth proxy can capture these too. Unfortunately, my understanding of ESPHome is not enough to resolve the errors during compilation:

Thank you for your efforts

I'm getting a similar error, did you ever get this resolved?

This is my yaml. Just added the Yaml to the end, and it doesnt like something...

Hi, Unfortunately, no. This post here was my last attempt to find a solution. I think esp_now should be standard component to esphome and tested with each release. There will be a lot products using this tech...

[roynasser]

Hi @dixonbg I've been able to get it to compile finally... What did it for me was to go into ESPHome menu for the device and select "Cleanup build files". I think it was caching stuff and not finding the espnow module... I hope this solves your issue too!

~~Trying to install this on a RasPi2040 and breaking in a similar way, I think. Getting "src\esphome\components\esp_now\esp_now_component.cpp:92:43: error: 'bssid' was not declared in this scope" errors.~~

NVM - ESPNow is an ESP32 only protocol. Won't work on a PicoW. Guess I need to order an ESP32 board.
