Simple Bluetooth LE multinode synchonization protocol

BLE Synchronization protocol

This repository include all the issues associated to the synchonization protocol implementation in bluetooth low energy devices here possibly I'll include more than one protocol and compare their performance.

syncble's Issues

General issues to have into account

Please have into account the follow considerations before to implement the synchronization solution:

1. Each slave device will be synchronized with the master who actually is considered as the "MASTER/BOUNDARY CLOCK".

2. The connection set up is independent of the application. therefore there is no a problem at low level using the BLE library developed on the repository https://github.com/Daparrag/Lib

3. The behavior of the finite state machine must be independent for each device, thus for each connection a unique instance of events and status has to be considered . This means that a connection handler is associated to specific status in the finite state machine; Since not all the devices will be in the same status.

4. Don't implement this solution for a single master and slave node please think in to include two or more additional devices.

Sequence id doesn't match in ble_ptp protocol.

The sequence ID for SYNC and FOLLOW UP as well the DELAY_REQ and DELAY_RESP doesn't match

you have to increment the sequence ID immediately after to forward the FOLLOW UP and DELAY_REQ packets.

Error transmiting the DELAY_REQ form the ptp_client

the ptp_client is transmitting the DELAY_REQ packet using a notification without check the peer_ready_to_receive flag

The ptp_client device must wait until the ptp_server enable the notification.
