Script does not connect

[AdminGithubAxiansAT]

Hi!
I found the bluetooth mac with the discovery [NEW] Device 44:17:XX:XX:XX:XX FR:RE22111XXXXXXX

now I'm trying to connect to the radoneye device with python2.7 radon_reader.py -b -v -a 44:17:XX:XX:XX:XX

but I only get following output
Connecting...
Failed to connect to peripheral 44:17:XX:XX:XX:XX, addr type: random
Failed, trying again (1)...
Connecting...

what I'm doing wrong?

thanks, kr

Did you run trust 44:17:XX.... in the bluetoothctl command?

Hi!
Thanks for your answer. I've done it right now. But still the same issue.

bluetoothctl trust 44:17:XX:XX:XX:XX
[CHG] Device 44:17:XX:XX:XX:XX Trusted: yes
Changing 44:17:XX:XX:XX:XX trust succeeded
:# ls
radon_reader.py
:# python radon_reader.py -a 44:17:XX:XX:XX:XX -v

Hi,

I'm facing the same issue on RD200 (Firmware 2.0.2)
$ bluetoothctl trust E8:31:XX:XX:XX:XX
Changing E8:31:XX:XX:XX:XX trust succeeded

$ bluetoothctl connect E8:31:XX:XX:XX:XX
Attempting to connect to E8:31:XX:XX:XX:XX
[CHG] Device E8:31:XX:XX:XX:XX Connected: yes
Connection successful
--> bluetooth symbol on RD200s display is on. So it seems to work.

But when running the script it fails to connect.

What version of python and bluepy are you running the script with?

[Loretomes]

Hi dicer,

• python version 3.9.2
• bluepy version 1.3.0

It's running on a raspberry pi 3B, if this means something.

EDIT: I've installed additionally python 2.7. Same behaviour:

$ python2.7 radon_reader.py -a E8:31:XX:XX:XX:XX -v
Connecting...
Failed to connect to peripheral E8:31:XX:XX:XX:XX, addr type: random

Connecting...

I just had a look and I'm running the script with python 2.7.18. On x86 hardware, but that should not be the problem. Maybe try with 2.7 just so we know whether it is a python problem or something else?

[Loretomes]

Thanks for taking a look on this. Yesterday I edited my last post. I've tried python 2.7.18 too, sadly with the same result.

The smartphone app shows firmware version 2.0.2. Which version do you have?

[AdminGithubAxiansAT]

I also still have the same problem. Also tried with python 2.7 and 3.7. Any ideas?

[AdminGithubAxiansAT]

It seems that something has changed in the device.

1. I removed "random" in the line DevBT = btle.Peripheral(args.address). after that the script connects to the radoneye
2. I changed the uuids to 00001523-0000-1000-8000-00805f9b34fb, 00001524-0000-1000-8000-00805f9b34fb and 00001525-0000-1000-8000-00805f9b34fb. After that the script does something...
   But the result is always 0 so there needs something to be changed, maybe the \x50 is wrong?

I don't use the app, but 1.2.4 is showing when the device boots up.
I guess that fits with what @AdminGithubAxiansAT found out. No idea what needs to be changed though. One of you could dump the BLE traffic the official app generates and have a look there. I guess some other IDs or commands might be needed?

[AdminGithubAxiansAT]

I have the app but can‘t find the version.
how can I do the ble traffic dump from the app?

[dicer]

Android can write all bluetooth packets to a file if you have the developer settings enabled. It's called "Enable Bluetooth HCI snoop log" on my device. The resulting file can be analyzed in wireshark afterwards.

I have the app but can‘t find the version.

If you connect with the RadonEye App the firmware version is shown at the bottom screen as 'F/W: V2.0.2'.

I'm also able to find out the same UUIDS 00001523-0000-1000-8000-00805f9b34fb, 00001524-0000-1000-8000-00805f9b34fb and 00001525-0000-1000-8000-00805f9b34fb with the help of nRF Connect app.

I've loaded the bluetooth log to wireshark and can see, that there are connections between smartphone and RadonEye (both as source and destination). But I've no idea how to step further. How to read out the lots of information wireshark offers?

I have only ios devices, no android. Seems that there is no app to trace that with ios. Is it possible that you upload the trace?
