Implementation of Texas Instruments Unified Network Processor Interface frame protocol in Go.
UNPI is used by Texas Instruments for communicating with many of their Network Processor microcontrollers, specifically this library was written to support the CC253X series of Zigbee sniffers flashed with the zigbee2mqtt Z-Stack coordinator firmware.
More information about UNPI is available from Texas Instruments directly.
Another implementation of UNPI exists for Golang, it did hold no license for a period and the author could not be contacted. This has been rectified, so it may be of interest you. This is a complete reimplementation of the library, however it is likely there will be strong coincidences due to Golang standards.
Add an import and most IDEs will go get automatically, if it doesn't go build will fetch.
import "github.com/shimmeringbee/unpi"This libraries API is unstable and should not yet be relied upon.
serialPort := // UART port providing a Writer
// Construct a SysReset
frame := &Frame{
MessageType: AREQ,
Subsystem: SYS,
CommandID: 0x00,
Payload: []byte { 0x00 },
}
// Send Frame to CC253X, blocking operation
err := unpi.Write(serialPort, frame)serialPort := // UART port providing a Reader
// Read from CC253X, blocking operation
frame, err := unpi.Read(serialPort)
if err != nil {
// Handle Error
}
// Use frame
