Nano 33 BLE - Sending data to AdafruitIO (Cloud)

Hi,

I am trying to use a bluetooth gateway (my phone) to send data from my Nano 33 BLE to the adafruit IO cloud server as feeds. I have successfully managed to publish some Bluetooth characteristic data to the phone app (IOS Lightblue) but when it sends data to the Adafruit IO cloud the data isn't recognized as 'feeds'. I am just wondering do I have to add some sort of BLE descriptor to each BLE characteristic with the feed tag name? As currently there is 4 bits of data being sent (BLE Characteristic & values) without any BLE Descriptor or tag names...

What doesn't help is all the AdafruitIO examples I see online are purely for Wi-Fi and not using bluetooth...
