I've bought a pair of 433MHz RF Tx Rx modules. (https://www.ebay.co.uk/itm/4X-433Mhz-RF ... 2901031330)
I've been struggling to find any information on getting them working on Android Things (Raspberry Pi).
My goal is to set up AT to detect the RF transmission upon a doorbell press and then notify my phone if i'm not in. I'm an Android dev so the software side doesn't phase me, but I'm new to IoT so any and all advice is more than welcome.
