Hi all,
I would like to write a program to auto connect the Ble. I had gone through connect address but had find that it is for Bluetooth client extension and there is no option for Ble extension. Is there any way that i can connect to ble .
Hi Femilda,
- First you have to connect your device once, to find out its address.
- You then store the address in a TinyDB. I used the tag "microbit", but of course you can use anything you like.
- If you start your app, find out if the address is stored, and if yes, use connect with address, like this:
- The next time you start your app, you will find the address in the TinyDB and you can connect like this:
Of course your BLE device should be turned on and within range.
Use the BLE extension shown in Anke's post.
If you need guidance on connecting BLE, use this tutorial: The Internet of Things: Data Acquisition and Analysis
or more precise, follow the tutorial described in the link here : 0_Preparation_Teacher Guide_L2IoT1_Internet of Things_20220901.docx - Google Docs
The tutorial is for micro:bits, but for other BLE devices the procedure will be similar.
The tutorial has a slightly older BLE extension that will give problems on newer phones, but if you exchange it with the one indicated by Anke, you should be fine, at least I was.
