I have purchased a MDEK1001 kit few weeks ago. After setting up anchors and tag and confirmed performances in a simple 2 by 2 meters square, I’m looking now towards adding a gateway node to this network.
After following the steps in the gateway setup pdf file in the documentation package, it turns out the bridge can’ t detect others nodes in the network resulting in an empty RLTS manager web GUI.
After investigation, I have found 2 possible issue:
The bridged DWM1001 UWB communication is off - I have no possibility to turn it back on. It looks like once the node is setup as a bridge in the network by UART commands (after nmb), the bluetooth and UWB signals turn off.
The PI image mentioned in the pdf is v2.1 while we are using v2.0 from the documentation package. Does that can cause a compatibility issue between the PI and the DW chip ? I could not find the 2.1 file. If you do have it, can you please provide it ?
When the device is in Bridge mode, the BLE is turned OFF due to the strict timing between the firmware and the Linux Kernel module on the Raspberry Pi. Bluetooth would cause latency for the backhaul communication.
If you use the Raspberry Pi image provided on the link below (Documents → Raspberry Pi 3B Image for DWM1001C) then it should work
Please ensure your version of Raspberry Pi is 3B and no other version.
Also ensure that the 40-pin header is correctly soldered into the DWM1001-DEV board.
On the gateway, you should configure the gateway using the .conf file on the Raspberry Pi filesystem and not by the terminal. I would suggest to factory reset the firmware using: frst command and retry it.
the PI is plugged to a router with an ethernet connection.
After I typed the following command and completed the “4.1 Bridge node setup and configuration” and turn on pi + DWM1001DEV :
nis 0xXXXX (my network ID)
nmb
then I cannot access the UART anymore so I can’t use frst as you are recommending.
The double press on ENTER in the Tera Term does not allows me to enter the UART anymore.
The same way, the debugger is not even found through JLINK. (see image attached)
It really looks like everything is blocked on the chip once it has been set to bridge mode. Which would explain also why I dont detect the other UWB anchors and why they do not appear on the web RTLS interface.
Please, how can i reset factory the DWM1001-DEV without the UART? is there a hard resetting hardware button?
