Not connecting to BLE-devices

[snipah]

Hi Fabian!

Brief question: What do I need to do for the devices to connect?

1) BLE is enabled in SmartSolar and Shunt 2) Mac-App connected and MAC/ Key extracted

ESPhome compiles and boots up... but obviously nothing connects.

Hi, If you activate VERY_VERBOSE log level the ble tracker will print all devices it found and the mac addresses. It must be among them.

[snipah]

Thanks! But the keys extracted from the SQL-DB should be the correct ones? Will try but VERBOSE makes the ESP veeeeery slow, obviously :) Will report back!

[Fabian-Schmidt]

Use the USB connection when logging in VERY_VERBOSE and increase the speed by setting baud_rate: 2000000 (I got an CP2104 and they support baud rate of up to 2mbit).

The keys extracted look correct. ESP Home will refuse to build if they are too long or short. When the device is found I validate that the key might be correct by comparing the first byte of the key.

Now it works! Truma and Victron on one device, but I can't get the log to work anymore: ERROR Logger is not configured!, even though a have

logger: level: DEBUG

configured. But at least it is working now!

On to adding Topeka and getting the log up and running at least to be able to check if everything if working properly.

Thanks a lot for your support !

[Fabian-Schmidt]

What was the issue? As a lesson learned for others.

[snipah]

First of all: Everything seems to be fully working now without errors and without losing connection. Is it better to turn the debug-log off now? What do you think?

I can think of two possble reasons, why it did not work: 1) The db-extract gave me the wrong MAC-address. Might be, because I'm on Mac. Your tip with the "VERY VERBOSE"-Log was great! 2) Because of 1) I was unable to tell, which key belongs to which device! But to the key have to be in quotation marks? I tried without and now it is working.

If anything else comes to my mind, I will add it here!

Anyway: Thanks a lot!
