GitHub - liweiyap/metawear-impl: Testing MetaWear device from MbientLab on Linux

Board Information

Code tested and produces same results with MMR and MMR+. Both devices have the same:
- Hardware revision: 0.4
- Firmware revision: 1.5.0
- Model number: 5

Host Device Information

Ubuntu 16.04
Linux Bluetooth library, version 5.54

Description of Problem

Expected to print the message Board initialised from initBoard() with a status of 0 (MBL_MW_STATUS_OK).
Instead, observed the message Error initialising board from initBoard() with a status of 16 (MBL_MW_STATUS_ERROR_TIMEOUT).
The steps leading up to this behaviour in main.cpp:
1. A WarbleGatt object is first created using the device MAC address and the host HCI address.
2. Connection to the device MAC address via warble_gatt_connect_async is successful.
3. An MblMwBtleConnection object is created using our own implementations of the GATT operations.
4. An MblMwMetaWearBoard object is instantiated using mbl_mw_metawearboard_create.
5. Finally, initBoard() calls mbl_mw_metawearboard_initialize, which initialises the internal state of the MblMwMetaWearBoard object. This is where the observed message is printed.
As a result, mbl_mw_sensor_fusion_set_mode(board, MBL_MW_SENSOR_FUSION_MODE_IMU_PLUS) throws a std::out_of_range exception.

SDK

MetaWear C++ SDK, version 0.18.4
Ubuntu 16.04
Self-contained piece of MetaWear SDK calls that replicates this issue is found in main.cpp. The entire code can be copied/pasted and run, assuming that the following dependencies are also installed:
- Warble (version 1.1.5) for setting up Bluetooth LE connection
- Boost to help with UUIDs
All the output from stdout/stderr (with the message Error initialising board and the status of 16 for MBL_MW_STATUS_ERROR_TIMEOUT near the bottom):
