tessel / ble-ble113a Goto Github PK

I have connected to an Arduino based BLE Slave and am listening for serial commands on it right now. Can't seem to find a good way to explicitly write out and listen to it through the Tessel BLE api.

Here is the device (LightBlue Bean)

{
    "services": {},
    "rssi": -52,
    "advertisingData": [
        {
            "typeFlag": 1,
            "type": "Flags",
            "raw": {},
            "data": [
                "LE General Discoverable Mode",
                "BR/EDR Not Supported"
            ],
            "byteOrder": "BE"
        },
        {
            "typeFlag": 6,
            "type": "Incomplete List of 128-bit Service Class UUIDs",
            "raw": {},
            "data": [
                "a495ff10c5b14b44b5121370f02d74de"
            ],
            "byteOrder": "BE"
        }
    ],
    "address": "194.45.205.114.57.208"
}

Without the passkey display and passkey entry events it is impossible to connect to a passkey enabled BLE device.

Here is the output from trying to run the example:

The first byte should be an 0x80, instead there are three nonsense bytes (0xef, 0xbf, 0xed) so there may be an issue with the UART peripheral in T2 firmware.

Add code of conduct badge, a la tessel/project#190

See relevant forum issue for more details. I've made a forum post on the Bluegiga website about the issue.

I tried using your example by running it directly from the example directory and my iphone does not pick up on it.

npm init
npm i tessel --save
npm i 

Then in the ble-advertise.js

var tessel = require('tessel');
var blelib = require('ble-ble113a');

var ble = blelib.use(tessel.port['A']);
// var ble = require('../').use(tessel.port['A']); // Replace '../' with 'ble-ble113a' in your own code

var interval;

then

tessel run ble-advertise.js

I get started advertising... but with nothing showing on my iphone.

We need to throw an error when someone tries to send an advertising packet that is great than the maximum number of bytes (which I believe is 32).

Any UUID with dashes, such as 12ad43a2-a21b-d321-afd3-864ab23a1111 will not be parsed into a pure UUID.

The feature to change the transmission power has been requested on the forums.

To do this, a function needs to be added to messenger.js (the agent that sends and receives packages from the BLE113) to send the correct packet. To do that, call the bglib. hwSetTxPower function and pass in a value from 0 to 15 to sent the transmission power. 15 is the highest. Then, expose the function in index.js, where the BluetoothController will ask the messenger API to send the message and receive the response.

It would be nice to be able to set the advertising rate of a BLE module acting as a beacon.

To do that, we need to add a function to messenger.js which outlines the raw packet that is being sent over UART to the module. It will use the bglib.gapSetAdvParameters function. The function expects a 16 bit number describing the min interval, a 16 bit number specifying the max interval, and a bit mask to specify which advertisement channels are used. The interval argument can be between 0x20 and 0x400. The advertisement channel should probably be 0x07 to continue using all three channels.

Then, this messenger API function should be surfaced to the BluetoothController object in index.js.

The connection_status event is not being fired when trying to connect to an iOS device. See more details and test code on this forum post.

Bonus points if you make example code that other people can use to integrate Tessel BLE with iOS and/or Android

On the order of 1-2 minutes to do an unfiltered service discovery. Not sure if this is a function of the Tessel or BLE113.
