Immediate disconnect if ~ >3meters away #1

Open raphmur opened 1 month ago

raphmur commented 1 month ago

Hi there, Nice work

My config: nodeMCU form factor, with ESP-WROOM-32.

In installed your component, all good. Paired the keys while in the car.

My issue: Immediate disconnect if getting too far away (about 2 / 3 meters, and especially behind by house door.

Any idea on the signal level threshold or anything around this? Is ESP32 BLE powerful enough?

I have captured the logs below (only putting relevant parts):

My issue: Immediate disconnect if getting too far away (about 2 / 3 meters, and especially behind by house door.

Well, I haven't tested BLE range at all yet. The video I made was literally the first test I made w/ the Watchy. The rest of my dev and tests were done using an AZ-Delivery ESP32-WROOM-32 devkit (same as you, AFAIU) plugged in about 3 meters away from the car, behind a 20 cm brick wall.

I can't really say more right now :/
