So I built a little breakout board for the DWM1001 and I have only connected
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.
There is more than 1 ground on the DWM1001.
Please see the castellation in the doc below :
Have you connected all of them ?
[color=#333333]Yes, the breakout board has a common ground plane and I beeped all the GND pins to make sure they are connected.[/color]
Hello, have you solved your problem? I have the same problem now.
No, never did. Moved on to a different solution.
I saw in the website below that someone can use the USB to TTL module to connect to the DWM1001 and enter the shell mode. But I can’t.
It looks like you have swapped the VCC and GND lines.
I have used this and it worked for sure:
18: UART_RX - connect to e.g. RPI UART TX
20: UART_TX - connect to e.g. RPI UART RX
