During the last days I logged every 10 min some other handles and wrote the results into a logfile. I have done this for three different sensors.
First all the “easy” ones, they do not change at all and are the same on all three sensors, while 0x03 is the name “Flower care” in ASCII:
0x02: Characteristic value/descriptor: 02 03 00 00 2a
0x03: Characteristic value/descriptor: 46 6c 6f 77 65 72 20 63 61 72 65
0x04: Characteristic value/descriptor: 02 05 00 01 2a
0x05: Characteristic value/descriptor: 00 00
0x06: Characteristic value/descriptor: 0a 07 00 02 2a
0x07: Characteristic value/descriptor: 00
0x08: Characteristic value/descriptor: 02 09 00 04 2a
0x09: Characteristic value/descriptor: 0a 00 14 00 00 00 f4 01
0x0e: Characteristic value/descriptor: 01 00 ff ff
0x15: Characteristic value/descriptor: 98 00
0x1d: Characteristic value/descriptor: ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff
0x2f: Characteristic value/descriptor: 00
0x31: Characteristic value/descriptor: fb 34 9b 5f 80 00 00 80 00 10 00 00 04 12 00 00
0x32: Characteristic value/descriptor: 0a 33 00 fb 34 9b 5f 80 00 00 80 00 10 00 00 00 1a 00 00
0x33: Characteristic value/descriptor: 00 00
0x34: Characteristic value/descriptor: 1a 35 00 fb 34 9b 5f 80 00 00 80 00 10 00 00 01 1a 00 00
0x37: Characteristic value/descriptor: 02 38 00 fb 34 9b 5f 80 00 00 80 00 10 00 00 02 1a 00 00
0x3c: Characteristic value/descriptor: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
0x3e: Characteristic value/descriptor: 00 00 00
Then there are two handles that stay the same, but are different on every sensor, I didn’t checked it, but probably s.th. like MAC, serial etc:
0x17: Characteristic value/descriptor: 18 f6 45 03 a2 13 97 bb a1 2c
Characteristic value/descriptor: d6 85 2f 13 06 19 c6 c1 cb 3a
Characteristic value/descriptor: 06 5d 64 8f b7 7b 85 79 42 d7
0x1f: Characteristic value/descriptor: 29 d9 77 2e 97 49 a3 8a 9f 25 56 13
Characteristic value/descriptor: e7 aa 1d 3e 33 43 f2 f0 f5 33 ff 49
Characteristic value/descriptor: 37 72 56 a2 82 21 b1 48 7c de 09 68
Then we have our values, 0x35 is empty in my case, 0x38 has battery-level and firmware version:
0x35: Characteristic value/descriptor: 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
0x38: Characteristic value/descriptor: 52 13 32 2e 36 2e 36
By now, I do not think that they changed the handler for the above values, but may be you have so send a command or what ever, to get them.
Normaly, handle 0x35 should have values like the following:
Characteristic value/descriptor: d0 00 00 01 02 00 00 2f 6b 01 00 00 00 00 00 00
Characteristic value/descriptor: c9 00 00 23 01 00 00 19 42 01 00 00 00 00 00 00
Characteristic value/descriptor: cf 00 00 0d 00 00 00 1c f2 01 00 00 00 00 00 00
Characteristic value/descriptor: cb 00 00 00 00 00 00 1c 3c 02 00 00 00 00 00 00
Characteristic value/descriptor: e7 00 00 00 00 00 00 2a 00 02 00 00 00 00 00 00
Characteristic value/descriptor: ec 00 00 34 00 00 00 02 00 00 00 00 00 00 00 00
Characteristic value/descriptor: cb 00 00 00 00 00 00 1c 3c 02 00 00 00 00 00 00
Characteristic value/descriptor: cb 00 00 00 00 00 00 1c 3c 02 00 00 00 00 00 00
Characteristic value/descriptor: ec 00 00 34 00 00 00 02 00 00 00 00 00 00 00 00
Characteristic value/descriptor: cb 00 00 00 00 00 00 1c 37 02 00 00 00 00 00 00
Characteristic value/descriptor: cb 00 00 00 00 00 00 1c 3c 02 00 00 00 00 00 00
Next one is the handler 0x41, I’m quite sure, that this is a counter or s.th. similar, because it constantly increases it’s value (three or four bytes, MSB is on the right:
0x41:
14.10.2016,01:20:51 Characteristic value/descriptor: ab 0b 21 00
...
16.10.2016,22:30:01 Characteristic value/descriptor: 50 d1 24 00
0x41:
14.10.2016,01:20:51 Characteristic value/descriptor: 5c fa 03 00
...
16.10.2016,22:30:01 Characteristic value/descriptor: 31 c2 07 00
0x41:
14.10.2016,01:20:51 Characteristic value/descriptor: 3e f5 03 00
...
16.10.2016,22:30:01 Characteristic value/descriptor: 4c c0 07 00
OK and finally the is handler 0x12, no idea what this one is doing, it keeps it value for some hours, then changes, the value on all three sensors is different, only once for round about 12 hours, all three sensors had the same value: “ff ff ff ff”.
0x12:
14.10.2016,01:20:51 Characteristic value/descriptor: fa 1d 15 fb
