Lowering baud rate
01/01/70 00:00
Really
01/01/70 00:00
Modified the code in Master and Slave
01/01/70 00:00
Haven't seen full code - slave protocol state fully cleared?

Stop fooling yourself

why didn't you before posting updated code

How to reset?
01/01/70 00:00
Hard reset by doing a hard reset.
01/01/70 00:00
Errors gone

absolutely
01/01/70 00:00
worse in the real world
