Seeking Feedback -- Would You Be interested in Roadtesting a Bluetooth®︎5-capable Dev Board?

rscasny

imageI am planning on running a roadtest on the following rapid development board for battery-optimized Bluetooth® 5 solutions with the MAX32666 Arm® Cortex®-M4 processor with FPU. The board also has a 6-axis accelerometer/gyro, RGB indicator LED, and pushbutton.

If you have the time, I'd appreciate you voting in the poll below. It helps me gauge interest and the number of kits needed.

Here is some documentation on the board:

  • Yes, a good device it is.

    In Bluetooth, I think that Bluetooth SIG has already released standard 5.4. The bluetooth5 itself has several new features included than from previous one(Bluetooth 4). One of them is that it is capable of direction finding. There are basically two methods for direction finding AOA and AOD. Both require special antenna design requirements to be more accurate.

    This board in my understanding is similar to the one from SILabs that has EFR32 microcontrollers.

    It would be interesting to see someone blog about using BT5 in a direction-finding application.

    Very hard to implement with Maxim MCU according to my experience. Open source BLE stack which they provide has very limited support for advanced features. Last year, they even removed text "supporting LE Audio, angle of arrival (AoA), and angle of departure (AoD) for direction finding" from MAX32655 datasheet (document rev. 2 has it, rev. 3 has not).

    I recommed setting goals lower. Working with such open-source stack is very hard and you will be happy when implementing basic GATT in less than 3 workdays (except running basic examples, of course). The minimalistics example has over 1700 lines of codes in multiple files, and it runs only basic build-in services.
