Scan works, but querying with MAC address doesn't
I'm on Arch Linux and the device is paired. aranetctl --scan works:
$ aranetctl --scan

I am not able to reproduce this myself. Can you access GATT service using different programs? For example bluetoothctl?
bluetoothctl
menu gatt
list-attributes [device_mac]
Doesn't seem to be working with bluetoothctl either:

This might be an issue with BlueZ.
For me version 5.50 is working. (bluetoothd -v)
Additional data point:
Running on Raspberry Pi 3, buster
bluetoothd -v reports 5.50
But the aranetctl traceback is a bit different, most notably it reports bleak.exc.BleakError: Characteristic with UUID f0cd3001-95da-4f4b-9ac8-aa55d312af0c could not be found!

@joconor
What characteristics do you see under 0000fce0-0000-1000-8000-00805f9b34fb service?
Do you see f0cd1503-95da-4f4b-9ac8-aa55d312af0c or f0cd1504-95da-4f4b-9ac8-aa55d312af0c?
Which version is your Aranet running?
Same issue on Fedora 39.

Make sure you have paired Pi to Aranet and other devices (like phone app) is not connected to it.
Hi Anrijs, thank you for your advice. It seems pairing doesn't really go as expected.
admin@raspberrypi:~ $ bluetoothctl

The pair command doesn't seem to do much? I don't get any confirmation about the pairing process. It just keeps repeating this:
[CHG] Device C2:DB:C0:DC:E4:55 ManufacturerData Key: 0x0702

Update:
After I unbonded the device from my phone, I was able to get the following:
[bluetooth]# connect C2:DB:C0:DC:E4:55
Attempting to connect to C2:DB:C0:DC:E4:55
[CHG] Device C2:DB:C0:DC:E4:55 Connected: yes
Connection successful
[CHG] Device C2:DB:C0:DC:E4:55 Connected: no
So it seems it automatically disconnects as soon as possible? Then if I try using aranetctl, I get the same error I mentioned above.
Any ideas?
Thanks!
After pair command, you should see PIN input and Aranet screen should show it (same as when pairing with phone)
Try following this instruction:
Open bluetoothctl: sudo bluetoothctl
Enable passcode support: agent KeyboardOnly
Enable adapter: power on
Scan devices: scan on
When found your device, stop scan: scan off
Pair device: pair <DEVICE_ADDRESS>
Disconnect if automatically connected: disconnect <DEVICE_ADDRESS>
Exit from bluetooth ctl: exit
if that fails, reboot and try again
Hi Anrijs, I actually managed to do it. This was the trick though:
[bluetooth]# remove C2:DB:C0:DC:E4:55
[DEL] Device C2:DB:C0:DC:E4:55 Aranet4 00523
Device has been removed
[bluetooth]# trust C2:DB:C0:DC:E4:55

[bluetooth]# scan on

And then it started working. Thank you for assistance!
I would like to add the solution for me.
None of the above worked for me, but it got me close.
- I didn't realize, you must be connected to the aranet device with bluetooth BEFORE you run your python program to connect to it.
- Scanning for it will be successful at long ranges in my experience, but in order for the device to not pair and then immediately unpair, as others experienced as well, you must have the aranet device VERY close to your system. I put it 1ft away, re-ran the pair command and BAM. I was asked for a PIN, and the aranet device suddenly displayed a number. Typed it in and was connected
At that point, the python programs all worked, which specified the MAC and requested current readings.
Before that, only the scanning python examples worked.
My dumb self went and upgraded from a Raspberry Pi Zero 2 W to a Raspberry Pi 5, trying to get this to work. That was never the problem. It should work on any Raspberry Pi I bet. I haven't tested again with the zero 2w though.
