Are you sure your Characteristic UUID is correct? If you want to confirm this, use the following: "call BluetoothLE1.GetCharacteristicsForService" method using your service UUID as the input parameter.

I sure my UUID is correct.Because I can write Characteristic.And I don't find "call BluetoothLE1.GetCharacteristicsForService"method in AI2.
I use the extonsion is downloaded on the MIT website.

Looks like you could be using an old version of the BLE extension.
--
I am not sure why it is so difficult to find a link to the correct version of the extension, as I too had problems.
All it takes is a clear simple html link to be placed in a prominent position, with some h1 or h2 headers saying "New BLE extension", on the webpage, such as this one:
or even this one.... http://iot.appinventor.mit.edu/#/bluetoothle/bluetoothleintro.
Instead, I had to open up this pdf tutorial to find the link and download the correct extension (see bottom of page one).
Note, for full reference of new ble methods / block functions refer to the above link.
If you look in the FAQ (FAQ for Bluetooth/BLE and micro:bit) under the Bluetooth headings, you will find updated pointers.
We were promised that the right iOT versions will be more visible soon. (Try find the micro:bit extension for example ;-)
Keep your fingers crossed.

@Ghica / @Abraham Maybe as a suggestion, you should put the date of when new BLE extension was released. This will act as a trigger for people who assume they have the correct version.
Bluetooth/BLE
E.g.
Bluetooth/BLE
BLE extension (released July 2017): http://iot.appinventor.mit.edu/assets/resources/edu.mit.appinventor.ble.aix
edu.mit.appinventor.ble.aix
edu.mit.appinventor.ble.aix

There was already a date, but maybe it was as hidden as the pointers to the extensions.
I tried to improve on it.

Hi..Do you have some suggestions??
Please, I told you already twice: do not write to me privately!
No I do not have any suggestion. Install the new extension, look into the documentation and go from there.
