Experimental BLE project showing how IO can be made with an App over BLE. Pointer to matching App will be added when ready, initially this works with: - Android App [nRF-Master Control Panel], supports Write,Read,Notify - Android Project [BluetoothLeGatt]

Dependencies:   BLE_API mbed nRF51822

This is an experimental project for BLE (Bluetooth LE == Bluetooth Low Energy == Bluetooth Smart).

  • It supports general IO over BLE with Read/Notify/Write support.
  • It is compatible with FOTA using Android App "nRF Master Control Panel" (20150126)
  • IO supported by:
    • Custom Android App is in the WIKI under: Android-App, developed from Android Sample "BluetoothLeGatt"
    • Android App: nRF-MCP (Master Control Panel)
    • iOS App LightBlue.
    • General HRM, HTM, Battery and similar apps should be able to access the matching services.
  • It includes combinations of code from other projects, alternative code included can be tried by moving comments (, //)
  • 20150126 bleIO r25: It compiles for both "Nordic nRF51822" and "Nordic nRF51822 FOTA" platforms
  • 20150126 The matching bleIO App (in wiki) doesn't support FOTA yet, use Android App "nRF Master Control Panel"

Feedback and ideas greatly appreciated!!!

prussell 5:d36bbb315e31 110 All the 16-bit Attribute UUIDs defined in the adopted specifications use the above base.
prussell 5:d36bbb315e31 111 Generating a 128 bit UUID for custom profiles: For the 128 bit UUID, please refer to The ITU-T Rec. X.667.
prussell 5:d36bbb315e31 112 You can download a free copy of ITU-T Rec. X.667 from http://www.itu.int/ITU-T/studygroups/com17/oid/X.667-E.pdf.
prussell 5:d36bbb315e31 113 In addition if you go to http://www.itu.int/ITU-T/asn1/uuid.html, you can generate a unique 128-bit UUID.
prussell 5:d36bbb315e31 114 Latency: Refer to Core Spec V4.0, Vol 3, Part F - 3.3.1, which is "Ready by Type Request".
prussell 5:d36bbb315e31 115 If you look at the PDU, you have to send 2 bytes UUID for adopted profiles and 16 bytes UUID for custom profiles.
prussell 5:d36bbb315e31 116 There is additional 14 extra bytes over head for the custom profiles for "Ready By Type Request Method"
prussell 5:d36bbb315e31 117 Note: All attribute types are effectively compared as 128-bit UUIDs, even if a 16-bit UUID is provided in this request or defined for an attribute. (See Section 3.2.1.)
prussell 10:ee3a359f7d3f 118 A suggestive alternative will be to use a notification method, (see 3.4.7.1), where you don't need the 128 bit UUID or the indication method (see 3.4.7.2) */
