BLE UART for micro:bit in the next release

[KSao]

Hi there,
I'm using App Inventor to create an IoT App using micro:bit.
I found the following description on MIT App Inventor + Internet of Things, so I posted this.

"Please Note: Some of the tutorials and other materials on this website may be outdated, resulting in non-functioning apps. We are currently creating new Internet of Things components and tutorials. For specific technical questions, search or post on our community discussion forum. -- The App Inventor Team 3/31/22"

I think that UART is the most important feature (profile) in micro:bit BLE. Although there are other functions, UART can be substituted.
I hope that UART is supported in the next release too.

Currently, it is difficult to use UART with the methods of use that are open to the public, but I am using it as follows based on various information and my trials.

The extensions I am currently using are:
edu.mit.appinventor.ble-20200828.aix
com.bbc.microbit.profile-20200518.aix
The extension that utilizes UART is Microbit_Uart_Simple.

Using this extension, we are able to send and receive data as follows.

The code of App Inventor for sending.

(Enclose the sent message with "#" and "##". The octets to be able to send is 16. I know this is a rule of thumb and an interim method.)

The code of Makecode for sending.

The code of App Inventor for receiving,

The code of Makecode for receiving,

I'm sure there will be a lot of interest in the new App Inventor material, especially now micro:bit V2 is well established, which has a built-in speaker and microphone.

Hi, I have made a tutorial a while ago about BLE, UART and Micro:bit:
part 1:

App Inventor, Micro:bit and UART

App Inventor, Micro:bit and UART Somehow, communicating with a micro:bit via UART is more difficult than it should be. For now, using the extensions as indicated in this tutorial, will ensure that everything works. This tutorial is intended to show how to use Bluetooth Low Energy (BLE) to send messages to a micro:bit. This can be used to control a toy robot car or any device that uses a micro:bit as its brain. This first part will only cover the basic communication with a micro:bit via BLE. A…

and part2:

Controlling a Ringbit car with a micro:bit via BLE and UART

This is the second part of a tutorial about BLE, micro:bits and UART. I assume that you have seen and understood the first part, to be found here: https://community.appinventor.mit.edu/t/app-inventor-micro-bit-and-uart/ This is the Ringbit car: [IMG_20211105_134808851][IMG_20211105_134837720] It costs about $25, not including a micro:bit v2, which should cost less than $20. It is fairly easy to assemble, but it does not look very sturdy. There are many alternatives available in a similar p…

Maybe there is still something in it that interests you, and yes, good integration of UART into the BLE and micro:bit extensions is long overdue.
