Did the Bluetooth UUIDs change?

[eisenhowerj]

Hello, I bought the Airthings Wave specifically because of this project. Anyway, my unit seems to have a different set of UUIDs than the python script is looking for.

Error:

root@radon:~/wave2# python read_wave.py 10 Traceback (most recent call last): File "read_wave.py", line 197, in wave.connect() File "read_wave.py", line 150, in connect self.datetime_char = self.periph.getCharacteristics(uuid=self.UUID_DATETIME)[0] File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 508, in getCharacteristics rsp = self._getResp('find') File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 407, in _getResp resp = self._waitResp(wantType + ['ntfy', 'ind'], timeout) File "/usr/local/lib/python2.7/dist-packages/bluepy/btle.py", line 368, in _waitResp raise BTLEGattError("Bluetooth command failed", resp) bluepy.btle.BTLEGattError: Bluetooth command failed (code: 10, error: No attribute found within the given range)`

At first I thought something was wrong with UUID_DATETIME but after singling out each wave.read, none of them work. After picking around and trying to do my own bluetooth debugging, I think the UUIDs have changed.

I know I'm "talking" to the right device:

[A4:DA:32:27:6A:34][LE]> char-read-hnd 0x0030 Characteristic value/descriptor: 41 69 72 74 68 69 6e 67 73 20 41 53 [A4:DA:32:27:6A:34][LE]> # Airthings AS <----------------- [A4:DA:32:27:6A:34][LE]> char-read-hnd 0x002c Characteristic value/descriptor: 47 2d 42 4c 45 2d 31 2e 32 2e 34 [A4:DA:32:27:6A:34][LE]> # G-BLE-1.2.4 <-----------------

Let me know if other details are required. I simply turned on device, paired with phone (while I'm testing, bluetooth is turned off on phone) and it went through a firmware update then rebooted.

Do you have a 2nd generation Wave? If so, then have a look at this issue https://github.com/Airthings/wave-reader/issues/6

[eisenhowerj]

Well damn, thats what it was (swapping the UUID). I did notice at one point something in the bluetooth saying that it was an Airthings Wave+ and I did try the waveplus-reader.

In the other thread you mentioned there is currently no support for Airthings Wave 2nd gen...should I return it and get an Airthings Wave 1st gen?

[orjangj]

By "no support" I meant that we do not have a dedicated script to read values from Wave2, but you should be able to get the waveplus-reader script to work with your Wave2 by applying the changes discussed in issue #6. So no need to get a 1st gen Wave if you want to keep your 2nd gen 🙂

Ah ok, thanks for the reply
