[Story] - LekaOS BLE v1.0.0

[ladislas]

Introduction

BLE communication with the iPad is one of the most important feature of LekaOS. Without it the robot is useless and its presence allow us to:

• control the robot
• debug/log what's going on
• tests new functionalities (FOTA, scheduling, etc.)

Roadmap

1. Setup a basic working example using mbed
2. Test the integration with timed tasks and scheduling
3. Implement Leka Communication Specifications

1. Setup a basic working example using mbed

This first step is really easy: use the examples from mbed-os to create a simple working example of BLE for Leka to pave the way for future developments

This must include:

• read, write and notifications services/characteristics
• the use of predefined services (battery) and proprietary services (temperature, firmware version, basic command)

2. Test integration with timed tasks and scheduling

Through out our development we will need to start tasks and stop them. Gaining a deeper understanding about how this will work between BLE and mbed os is paramount as all future development will rely on that.

More information in #1 - #1 (comment)

This must include:

• starting a long running thread
• stoping a long running thread anytime
• starting again from the beginning
• starting again where we left off (if possible)

3. Implement Leka Communication Specifications

We'll review, update and implement the Leka Communication Specifications in parallel with the iOS app.

The main goal is to have the two perfectly synchronised.

This must include:

• implement all the services/characteristics
• implement the command analyser
• a lot of testing

4. Mandatory commands

• implement reset command and test in case of infinite loop
