nube question

First venture into arduino. Building a custom lightsaber. For this build I am using a premade board for saber controls. Next build I will take a wack at my own board. That said, I want to make a ble proximity switch. Trying to basically mimic a smart key like in a car. I want to have the switch inline with the 3.7v power supply for the saber. I saw a switch for a 110v light using a tessel 2 board, relay & ble module. Too large for my application. I have purchased a beetle ble, a gravity 1 channel relay & a gravity vibration sensor. My hope is that the vibration sensor will wake up the beetle to broadcast a ble signal when the saber is picked up & the relay will allow power to the saber's controls while the connected ble device is present. So my question is two part. First is the hardware I purchased correct & is this even possible? Secondly is the code I found for the tessel board comparable with the Bluno board? I will try to attach a link to the tutorial I found.

Any & all help will be useful. Thanks.
