128 bit version for service id "FEA6"

[sultanmyrza]

I use ionic and run on android.
To connect to goPro bluetooth I use this packet

In code I connect like this

await BleClient.requestLEScan(
        { services: ["FEA6"], allowDuplicates: false },
        (result) => doSomethingWithResult(result)
      );

on android I got this error

V/Capacitor: callback: 74973120, pluginId: BluetoothLe, methodName: requestLEScan, methodData: {"services":["FEA6"],"allowDuplicates":false}
D/Capacitor: Sending plugin error: {"save":false,"callbackId":"74973120","pluginId":"BluetoothLe","methodName":"requestLEScan","success":false,"error":{"message":"Invalid service UUID."}}

But If I don't specify service id aka (it connects fine)

await BleClient.requestLEScan(
        { services: [], allowDuplicates: false },
        (result) => doSomethingWithResutl(result)
      );

But still want to know is there such thing? 128 bit version for GoPro service id "FEA6" 😅

Hello. The "Control and Query" service UUID is 0xFEA6 which is a 16-bit UUID. It is not possible to refer to this UUID as as 128-bit UUID. Note that UUID's in Bluetooth can either be 16 or 128 bits so this is acceptable behavior.

I've never used Ionic but I found this after a quick search:
"UUIDs are always strings and not numbers. Some 16-bit UUIDs, such as '2220' look like integers, but they're not. (The integer 2220 is 0x8AC in hex.) This isn't a problem with 128 bit UUIDs since they look like strings 82b9e6e1-593a-456f-be9b-9215160ebcac. All 16-bit UUIDs should also be passed to methods as strings."

So it seems that there might be some special handling needed for non-128 bit UUID's.
