b41T #1

I have an owon b41T which seems to use mostly the same protocol to the b35t this was designed for. I was wondering where you got the info you needed to create this, as I would like to modify it for the b41t. The app compiles and runs and connects to my meter and I can control the meter ok with the m5stack but the numerical values from the meter are never displayed. Any ideas? Thank you for all your great work :)

numerical not work but icons? info for reading: https://hackaday.io/project/12922-bluetooth-data-owon-b35t-multimeter info for reading and control: https://github.com/akemnade/owon-tools and of course some app for android phone (in my case) for experiments with reading and control like BLE Scanner and nRF Connect You can also uncomment lines 584-589 inside M5Stack_BLE_client_Owon_B35T.ino and check on serial console what information from the meter is coming. b35t reply bytes from 1-4 are value digits, You must check if b41t sending digits at this position
