I saw several applications but i didnt receive nothing.
i have downloaded application to my iphone: smartdata (microchip) and after connection, i receive all my ble unit data.

Thanks.

Hi again

Currently, App Inventor only supports Android......

So, the attached project is a basic template which you should test as-is at first (with your own UUIDs) then once it is working, you can modify it to suit your requirements.
BLE_RECEIVE_STRINGS.aia (193.4 KB)
What device is sending the data?

hi.

rn4871 (microchip)

Have you written a script for it? The m4871 and your App need to be on the same page to exchange data.

i have a circuit that has this chip and i configure it.
my unit send the data automatically after connection.
i have downloaded to my iphone the application of microchip:SmartData.
after i see my device name on the app and press it, it automatically connect an d move to receive mode.
After that, i see my text that i have sent on the screen.

Hi

The point is this - the App needs to know:

  1. what has been used to mark the end-of-data
  2. what has been used to delimit the values
  3. The Service and Characteristic UUIDs

If you know these, then it should be plain sailing :grin:
