Is software v9 not supported?

[jonadis]

I'm trying out this code on an ESP32 with a JK-BD6A17S8P
Only a few of the parameters are coming through with the rest either showing non-sensical values or non-printing characters.

Details from the App over Bluetooth:
Hardware Ver: 9.X
Software Ver: 9.01G

Example conversation from ESPHome log:

It looks like the response payload has changed. Does the BMS return this garbage periodically depending on the update/request interval?

Actually I just moved the pins on the ESP from 14 & 4 to

  tx_pin: GPIO16
  rx_pin: GPIO17

as it is my understanding that that makes use of the hardware UART: https://esphome.io/components/logger.html#hardware-uarts
and after that change I'm in good shape.

Perhaps I just had a loose wire and it was just the re-connection that solved it, or perhaps there's something to that hardware UART business. In any case thanks for putting together this awesome project.
