#92145 Ok so my idea is very simple. My car has a voice command button in the driving wheel, but the voice feature is not installed so it doesn't work. I thought about 3d printing a mount for a custom button that should open google assistant on my phone instead (or maybe if it works well i will rewire the existing button) because my phone is connected via Bluetooth to my car radio so I can listen to spotify or navigate using google maps.

So my question is, how should i connect this "Custom Voice Button" to my phone. I know that Bluetooth with something like a esp32 would be an option but I am worried that this will collide with the connection to my car. (Something like my phone deciding that the esp bluetooth connection should receive the audio) I have quite a lot of experience with Arduino and esp microcontrollers so the actual software is not a problem but I have no experience with using bluetooth and I dont know if this is a good apprhttps://19216811.cam/ https://1921681001.id/
oach.

Summary: Does someone know a better way of triggering google assistant from a digital signal than using Bluetooth with esp32 microcontroller?
