JKBMS JK-B2A24S20P version 4.3.4 #227

I am guessing that JKBMS JK-B2A24S20P version 4.3.4 Hardware Ver 10-.x-W

I am guessing that the new version of the JKBMS is not currently supported I have tried to communicate with it over Bluetooth and RS485 with no luck.

I can see that it tries to connect and send commands but no response is received.

I have the JK-B2A24S20P that was ordered in April and am not having issues getting device and cell data from it running on a Raspberry Pi 3. FYI, when there is an active bluetooth connection the led light on the BMS will stay on instead of blink. hardware_version 10.XG software_version 10.07

I have two BMS

BMS 1 JK-B2A24S15P HW: 10.XW SW 10.08 Bluetooth OK RS485 or via TTL no answer

BMS 2 JK-B2A24S20P HW: 10.XW SW 10.07 Bluetooth no connect. maybe Raspi Problem RS485 or via TTL I get an answer but the data are strange

Both BMS work perfectly via the app
