Trouble connecting to BX1

[dev-git]

Hi,

I'm trying to connect to the BX1 (HOLMAN_CO3111) with holmanctl (on a raspberry pi) but can't seem to get it to work. It looks like I can connect but then the connection instantly drops and I can't retrieve any of the settings or switch the timer on/off. Have followed your instructions for adding the BTX1 and they appear to have the same service UUID (c521f000-0d70-4d4f-8e43-40d84c50ab38). Have run nRF on my android phone and here's the content. Any help much appreciated. Thanks.

Did you ever get anywhere with this?

Did you ever get anywhere with this?

I gave up with the holman client and tried a few other Bluetooth clients. After some expermination, I settled on the Bleak Client which was stable and worked well. Here's some of my code that turns the timer on for 20 mins (from a RPi): https://github.com/dev-git/thepythonfiles/blob/main/gardenpi/bleak/write.py There should be some code around that reads the other settings (Battery/Watering status/etc) Hope that's useful.
