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?
