You forgot something i think ;)

var CLOCK_SERVICE_UUID =    '39e1FD0084a811e2afba0002a5d5c51b';
var CLOCK_CURRENT_TIME_UUID = '39e1FD0184a811e2afba0002a5d5c51b';

indeed :)
And there is also a minor issue when downloading big samples, I will update it asap !
Thanks

I try it but I have this issue:

calibrated EC porous = 1.47 dS/m
getHistoryNbEntries

/home/pi/node-flower-power/index.js:462
var data = data.readUInt16LE(0);

@kerautret: I submitted a PR against the forked version, as soon as the @Parrot-Developers folks merges it will work, or you can try my branch: https://github.com/oroce/node-flower-power/tree/history

@JeromeBouvard: could you help how could I parse the returned raw data? Or do I have to upload that to parrot cloud?

• Hi all, I propose my commits to fix null data and to shorten slightly the code like this:

FlowerPower.prototype.readData = function(service, uuid, methodeRead, callback) {
    this.readDataCharacteristic(service, uuid, function(error, data) {
        if (error || !data) callback(error || 'Error: no data');
        else callback(error, data[methodeRead](0));
    }.bind(this));
};

// and if you want read a characteristics
FlowerPower.prototype.getHistoryNbEntries = function(callback) {
    this.readData(HISTORY_SERVICE_UUID, HISTORY_NB_ENTRIES_UUID, "readUInt16LE", callback);
};

• I'm writing a module which synchronize flower power's data with the Parrot cloud, and an mini application with graphic interface web. If the BLE module is unstable, all is unstable :)

Would it be possible to provide the parrot firmware file 2016-09-14_hawaii-2.0.3_hardware-config-MP.bin in order to upgrade a flowerpower which has the first version of the firmware please? The parrot servers are no longer accessible I am very annoyed :).

Were you able to get yours updated? I'm missing something in my steps
