What is BluetoothGattDescriptor?
As referenced in Android doc for BluetootGattCharacteristic:
Problems reading BLE characteristic
I am sending a byte array of size 8 every one second from HC08 module using software serial on arduino nano.However, when i try to read characteristic from my android app, where i also read every one second, onChracteristicread gets invokes every time but the received data is always 0. I am reading from SERVICE_UUID: UUID = UUID.fromString(“0000ffe0-0000-1000-8000-00805f9b34fb”)
CHARACTERISTIC_UUID: UUID = UUID.fromString(“0000ffe1-0000-1000-8000-00805f9b34fb”)
, which I think are the complete form of FFE0 and FFE1. Did i miss any step?
Record Access Control Point last record command returns all records
Currently I’m working with glucose meter and communicating with it via BLE. At the moment there are 3 records. The problem is when I’m trying to get only last record stored on the device through RACP all records are returned instead.
Where do the unreadable characters come from in my bluetooth low energy advertiser app?
I have written a simple bluetooth low energy advertiser app to transmit a custom string in the adRecord part of the bluetooth low energy signal and there’s a bunch of random characters that appear and take up space that I would like to use.
