Tool/software:
We are experiencing issues with our isolated UART communication in a multi-pack battery system. The setup includes four battery packs:
- Two base packs, each with a BQ79652
- Two stack packs, each with a BQ79612
We communicate directly over UART with the first base pack (BQ79652), referred to as base1A. From there, the isolated UART is daisy-chained to stack1B (BQ79612), then on to base2A (BQ79652), and finally to stack2B (BQ79612).
- Direct communication with base1A works correctly.
- Communication with stack1B, through base1A, also works.
- However, any attempt to communicate with the third device (for example, base2A or stack2B) via stack1B fails.
Our question is: Should communications through multiple stacked devices work automatically once communication between base1A and stack1B is established, or is there special software/configuration required for supporting multiple stacked devices?
