i don't understand where error happens, "Error: Non-hexadecimal digit found" I'm try to connect to lego boost

Hi @vtolstov

The line in the debug output came from BLESession._get_dev_uuid().

2021-11-13 16:41:00,512 adtype complete 16b

So something strange happened around that function. I have added some more debug prints around that function with the commit 266bcc98bd23 in dev branch. Can you try with the dev branch and share what the debug print output?

[vtolstov]

thanks, now i have this log

@vtolstov Thank you for the quick reply! The line below indicates the failure cause:

2021-11-14 12:52:57,138 service class uuid for adtype complete 16b/3: 0000aa01-0000-1000-8000-00805f9b34fb,0000aa02-0000-1000-8000-00805f9b34fb,0000aa03-0000-1000-8000-00805f9b34fb,0000180a-0000-1000-8000-00805f9b34fb,0000fee8-0000-1000-8000-00805f9b34fb

This line prints out the return value from a bluepy API ScanEntry.getValueText() for adType complete 16b. I assumed that it returns only one UUID, but actually, multiple UUIDs are returned. This is not what I expected.

I have pushed a fix trial commit 3ffbde3 to the dev branch. Can you try it out? Wish it works well.

[vtolstov]

yes, thanks, i'm try it now

[vtolstov]

yes, now it connects successful.

[vtolstov]

now i don't understand why only one motor can works, but may be this is not related to scratch and pyscrlink

[kawasaki]

Thank you for trying it. One step forward :) Later on, I will work to merge the fix to the master branch. I'm not sure why only one motor works...
