#180985 - Two UART Responding to: ???'s previous message |
Is it too simple to use a device with two UART?
Then do B -> C -> A C (your unit) can directly send questions to A. B (not in your control) can send questions (potentially buffered and delayed) through C to A. If C have short questins that are quickly answered, then B will suffer quite short delays. To B, it will seem like A sometimes have to think a little bit longer before sending the answer. |
