BSSID Support - Forcing an esp32 to connect to a particular router/AP to prevent switching/'dropouts' on mesh networks

[ahaverty]

Hi, I'm wondering if this library could allow defining a BSSID, to lock the esp32 onto a particular access point.

For context, I have an esp32 controlling two switchbots upstairs, connected to home assistant.
My home is running a mesh network (Nest routers + Google Wifi x3).

A few times a day, the esp32 registers as unavailable for a few seconds.
I believe this is due to the esp32 sitting in between two nodes in the mesh network.

Looking through esp32 docs, this appears to be possible:
https://espressif-docs.readthedocs-hosted.com/projects/arduino-esp32/en/latest/api/wifi.html#begin

uint8_t* bssid sets the AP BSSID.

Unfortunately I wouldn't have the knowledge to make a PR here.

I have a full writeup over here, and @devWaves has kindly offered to support BSSID's in his switchbot repo, if this library becomes capable.

Thanks!

I have the same issue. I have a complete Ubiquiti setup where I meshing is disabled and the client is locked to an access point using the Ubiquiti network controller. Still I see short to intermediate disconnects. The client is running on an ESP32-S2 Feather board.
I was wondering, did you try this suggestion devWaves and if so, did it help for you?

client.enableLastWillMessage(lastWill, "expire");
