The Unpaid Backbone of Open Source: Solo Maintainers Face Increasing Security Demands
Solo open source maintainers face burnout and security challenges, with 60% unpaid and 60% considering quitting.
##BGLib BGLib is a Node library for sending and receiving packets from BlueGiga BLE devices (currently supports ble112 and ble113). It is currently being developed by Technical Machine to support our Tessel BLE module.
##Install
npm install bglib
##Examples
###Creating a packet
var bg = require('bglib');
var bglib = new bg()
bglib.getPacket(bg.api.systemHello, function(err, packet) {
console.log(packet.getByteArray()); // Returns buf< 0, 0, 0, 1 >
});
// Use Packet Mode if you don't have flow control
// It adds a length byte to the front of every packet
bglib.setPacketMode(true);
bglib.getPacket(bg.api.systemHello, function(err, packet) {
console.log(packet.getByteArray()); // Returns buf< 4, 0, 0, 0, 1 >
});
bglib.getPacket(bg.api.gapDiscover, [1, 0], function(err, response) {
bglib.getPacket(bg.api.systemHello, function(err, packet) {
console.log(packet);
/* Returns { mType: 0,
tType: 0,
payloadHighBits: 0,
payloadLowBits: 0,
cClass: 0,
cID: 1,
payload: <Buffer >,
packetMode: true,
callback: null }
*/
});
###Parsing Incoming Data
var incomingBytes = new Buffer([ 128, 38, 6, 0, 189, 0, 108, 189, 40, 93, 28, 216, 1, 255, 27, 2, 1, 6, 17, 6, 186, 86, 137, 166, 250, 191, 162, 189, 1, 70, 125, 110, 56, 88, 171, 173, 5, 22, 10, 24, 7, 4]);
bglib.parseIncoming(incomingBytes, function(err, parsedPackets) {
console.log("Parsed packets: ", parsedPackets);
// BGLib will automatically parse each packet into the values stated by the datasheet
// depending on what type of event/response it is. Below is an example for the discovered
// peripheral event that was passed in:
console.log(parsedPackets[0].response.packet_type) // 0
console.log(parsedPackets[0].response.sender) // buf< 108, 189, 40, 93, 28, 216>
console.log(parsedPackets[0].response.address_type) // 1
console.log(parsedPackets[0].response.bond) // 255
console.log(parsedPackets[0].response.data) // data object with flag types, raw data, etc
console.log(parsedPackets[0].rssi) // -67
});
The library will hold the current state of the packets so you can pass in pieces of a packet and it will return the entire parsed packet when it has all been passed in.
###Thanks JRowberg deserves a special shout-out. Some of the code is modeled after his Arduino bglib work.
