node-red and DWM1001-DEV

Ultra-Wideband

#1

Hi there,

to progress until there is an offical gateway with MQTT broker I wanted to use node-red on a RPI for prototyping.
By this one would be very flexibel in how to consume UWB information in terms of IoT.

I soldered a header to the DWM1001-DEV and placed it as a HAT on a RPI 2.
LEDs, are good. J-Link indicator is flashing red.

I disabled terminal emulation on tty and enabled it for serial useage in raspi-config.
See attached config of node-red’s serial node.

Unfortunetly I dont receive anything in nodered.

What am I doing wrong?

Thx!

Stefan

Have you tested your sequence via terminal? To wake up the UART comm on the module, you need to send ‘\r’ three times. Send once, wait for ‘@’ and send twice immediately afterwards.
