Hello,
I'm new to this forum and I have a basic knowledge of electronics, so keep that in mind.
I was wondering if someone could help me with my car's audio.
So I have this Bluetooth device that has an AUX output which I've connected to the car's AUX input and that's how I can play songs from my phone to my car's speakers via Bluetooth. Now, the problem is that when I turn off the engine (the music is still playing) and then go to start it again, the starter motor for the engine draws a lot of power and the Bluetooth module loses power and therefore the connection with my phone is being terminated. And when the engine starts I have to reconnect the phone and BT module and it's quite annoying. I've connected a simple USB power bank to get around this, but it's just a temporary fix and not very practical (i have to recharge it at home because it won't charge if you're drawing power from it).
So, my question is this: How can I make the BT module not lose power for those few seconds while the engine is being cranked?
Do I need some kind of a capacitor, or a relay or something? I have no idea. Can you please suggest a solution to this?
The BT module doesn't draw more than 2.5W of power.
