So just recently purchased the ESP32 and a TTL converted, I set everything up, and ran in debug mode. RJ45 is connected to the first RS485 next to the CAN.

On the converter, I can see the periodic tx, but RX is never triggered.

Here is the debug info: image

The converter being used: image

I do see the following warning about GPIO5, not sure if it's related: image

So this can be ignored. Tried the following: tx_pin: GPIO5 rx_pin: GPIO4

Shortly after I noticed the following picture: image

This would then be a confirmation that this specific seplos E10 v2 (rebranded as Apexium Apex) works with the software, baud rate 19200

Could you provide some more details about your BMS model? So you are able to talk to your BMS using this component now?

Pho3niX90 commented 8 months ago

Yes everything is working as it should

So the BMS in question is branded as a "Apex 48200", it's supplied by Docan/Apexium Apex BMS 48V200A-compressed.pdf

It is actually a Seplos E10 (v2), image Manufacturer Info: CAN:PNG_DYE_Luxp_TBB Part Model: 1101-JK06 Software Version: 16.7 Protocol Version: 2.0

Perfect! I will add the model to the list of supported devices and will close this issue.
