So I built a little breakout board for the DWM1001 and I have only connected
3V3 (11)
GND (12)
TTL RX to UART_TX(20)
TTL TX to UART_RX(18)
I then attach a terminal (teraterm) at 115200 and hit the Enter key twice within a second but I don’t get a response. Are there any other pins that need to be tied?
I can see the device via BT when it is powered up, so it is running correctly.
It looks like you have swapped the VCC and GND lines.
I have used this and it worked for sure:
2: SWD_CLK
3: SWD_IO
12: VCC
34: GND
18: UART_RX - connect to e.g. RPI UART TX
20: UART_TX - connect to e.g. RPI UART RX
