I'm trying to get a Qardio ARM BP monitor working with Linux/Bluez but
cannot seem to read any device characteristics with Bluez. My
interaction through bluetoothctl looks like this:
# menu gatt
# attribute-info 00002a35-0000-1000-8000-00805f9b34fb
Characteristic - Blood Pressure Measurement
UUID: 00002a35-0000-1000-8000-00805f9b34fb
Service: /org/bluez/hci0/dev_B0_49_5F_02_B5_61/service0400

# Attempting to read /org/bluez/hci0/dev_B0_49_5F_02_B5_61/service0400/char0410
Failed to read: org.bluez.Error.Failed
I have bluetoothd running with debug flags but nothing appears in the
debug logs. What am I doing wrong?
