Hi everybody,
I'm pretty new to all the arduino stuffs so sorry if i'm making some mistake, this is what i want to do:
I want to control my garage door via bluetooth,connecting it with my android device, but the problem is that i'm pretty far away from it, about 20/25 meters. My question is if it was possible to improve the range of the bluetooth module by any way, like an antenna.
If it is not possible could you gently tell me how can i change my project to make it work?
thank you for your time.
Depending on the Bluetooth you are using, at both ends, one gentle solution might be to change it. If you are using one like the HC-0x on Arduino, then yes 20m is certainly stretching the friendship, but a BLE module is good for 30m, and is a plug in replacement. $5, and no change to the code.
Note that this presupposes your Android is using BLE (BT4). If not, the BLE on Arduino will revert to BT2 and you lose the benefit of the extra range.
Failing that, WiFi may be a better bet. I submit that opening the garage door with a phone via bluetooth is well short of a bright idea anyway. If you must do it with a phone, at least the WiFi will probably auto-connect before you've got it out of your pocket.
I'm guessing a bit here but, if you really want to impress the girlfriend, you might consider a bluetooth module in the car, independent of the phone and simply acting as some sort of beacon, thereby absolving you from having to push any buttons
Ok, thank you sir for dedicating your time.
