I want to send a trigger to the tag from Pi or teraterm and want to use its I/O to turn on led is there any way to implement this method .
You can used the gateway image on the Raspberry Pi and use the UWB downlink data to raise an event on the module. On event receive you cal then toggle the GPIO.
Please have a look at the gateway quick deployment guide and firmware user guide / firmware api guide.
ok…I have one more query regarding if i flashed the chip with my program and written a code in python on pi to make GPIO HIGH is it possible to toggle D12 LED on DWM1001 kit with this kind of approach
