Man in the middle with simp bms

[bigmotherwhale]

Hello knoxsp
I am trying to use your "man in the middle" CAN bridge with the simp BMS, Im having trouble getting it to work with an atmega328 and the mcp2515 modules (8mhz) i don't know why but it takes along time for the BMS to recognise all the extra modules and when it finally does it only stays without going into error mode for a max of about an hour, I think the Arduino im using might be too slow to handle the messages?
I would also like to use the balancing function of the BMS so would it be possible to setup a filter in the code to allow the balancing commands to get through the other direction to the CMU modules? I have had a go at solving this but im not very good an coding. I hope you can help.
Kind regards
