RNP USART output

Other Parts Discussed in Thread: CC2530, REMOTI

Hi, I have the CC2530 RF4CE developers kit and am observing

the Usart output of the RNP target board. I see in the code where

the call is made to NPI_SendAsynchData but it looks like the output

is encrypted. A keydown event results in 13 bytes being sent out

but it's unclear what the relationship between the arguments of the

function are and the byte codes sent. Can someone tell me more

about how those bytes are formed and how I can parse/decrypt them ?

Thanks, Brian

It's all covered in the API:

Great ! I've been going thru the documentation, just hadn't gotten to that one yet.

I've a quite similar problem, because i want to steer a Khepera II Robot with RemoTI for demonstrating purposes. The easiest way is to send an string like "D,10,10\n" via uart.

I want to send this kind of strings from the small CC2530EB target board of the RemoTI DK to the Khepera II using the external UART interface.

How can i use the predefined functions to do so and at which position in the simple App target source are the key-values from the RemoTI recieved.

thanks in advance

Perhaps you will find it more simple to just build your application using the SimpleApp sample application as your template instead of RNP. Then you would be free to invent your own serial data protocol instead of having to create a possibly complicated translation layer between RNP and the serial port.
