Coding BLE on Raspberry Pi

[Vinnie Moscaritolo]

I noticed issues recently also, I am in the middle of moving my laptop development systems from MacOS to linux at the moment and can't get to debugging right now.. I would suggest asking the folks at Victron what they changed. -- let me know if you find anything out useful

Thanks for your great work!

What is the firmware version of your device. I already fail here:

[bluetooth]# connect E0:E2:D5:3C:XX:XX

Attempting to connect to E0:E2:D5:3C:XX:XX

[CHG] Device E0:E2:D5:3C:XX:XX Connected: yes

Failed to connect: org.bluez.Error.Failed

[CHG] Device E0:E2:D5:3C:XX:XX Connected: no

Is it about encryption maybe? Where to debug?

Thank you

OK I managed to get a connection after two tries -- maybe its a power saving thing?

I'll have to investigate. I noticed some undervoltage messages recently. Otherwise I'll check the forum. Thanks for your replies.

yes my smartshunt fails to communicate with the newer firmware v4.14

FIXED

You were right. It is a power issue. I switched off Wi-Fi for testing and it works now. At the moment I do not have physical access to the device to fix the power supply issue but problem solved 😊
