Help finding UUID for BLE


#1

Has anyone used the BLE with an HC-10. Ive got the BLE working with a separate app, but I can’t seem to figure out how to find the characteristic UUID to plug into thunkable.

Hey @jw01563daqgz

What sort of values are you getting from your Scan function?


#3

Im getting the device Names and id’s no problem. Im able to connect to the HM-10 with the connect by name function. its just when I try to transmit data that I’m having issues. Should I have to scan before I can send data ?

If you’re using android you just need to use the characters UUID: 0000FFE1-0000-1000-8000-00805F9B34FB (obviusly you must be connected to the device to transmit data)
Using iOS, I don’t know why, I’ve got problems too


#5

There is an app in the Google play store / Apple store which might be able to help you -

You can connect your device with the app and you can find the characteristic UUID from the connected device info.

Best,
