I have been missing some of the data on the PAB bus that has not affected the operation of the powerbar.
However when I started utilising features of the expansion box this showed up.
As I have not been decoding the details on the bus, I'm not sure if this was causing retransmits, errors etc
My V2 approach is to actually interact more directly with the PAB bus.
To that end Ill utilise MCP2551 and MCP2515 to decode the data, transfer that to the micro and then to the wireless.
This will provide me with a 2Mb/s full duplex connection between the micros and should allow for sufficient bandwidth to allow the extension of the bus.
In terms of data packet order, thats something I need to test, but even with my basic V1 design, didn't seem to be an issue.
Ill make sure I implement some sort of handling to ensure that packets are delivered in order across the wireless.
thanks for the tip.
