Breadboarding and Proof of Concept

A project log for BLEifying a Honeywell PM Sensor

The Honeywell PMS transmits data via UART; if you wanted to get data you need wires. Adding BLE means it can just advertise data wirelessly.

Past experience have made me realize I really should be strict in breadboarding components first before immediately jumping into soldering them onto some protoboards.

So here it is: the Honeywell PMS and an Espruino MDBT42Q breakout, together with a lipo battery and a boost converter.

The test code was easy and simple as well (copied almost verbatim from the Espruino UART docs):

var s = new Serial();
s.setup(9600,{rx: D14, tx: D15});
s.on('data', function (data) {
  print("<Serial> "+data);
