BLE connection

[FastZyx]

I ca pair the device with passcode 000000, but then i can't connect to it. The property page of the device (on Win7 pc), in bluetooth services tab, show 'unknown service'

OK, i've read something about BLE. It works in a different way than previous versions, there is no SPP profile but everyone can build his own custom service to transmit custom data.

There are some apps in play store that can scan and read data from ble devices, for example BLE Tool (https://play.google.com/store/apps/deta ... tool&hl=en)

There is no pairing procedure for BLE device. You can do it like with a BT 2.1 device on your android device.

but get an error in line "socket.connect();"

For V4, details about the BLE access can be found from the DFRobot Bluno page.

There is an app for iOS that makes using the HM-10 easy to use. It is for a single pin output. There is also a link the sketch for it. I used it with Arduino Nano, HM-10, a Relay, junction box, and an outlet to turn my room light off at night without getting out of my bed. The app is FatBeard HM10 here https://itunes.apple.com/us/app/fatbear ... 32512?mt=8
