Issue with Responsive Mode

Hello Everyone,

I have recently had a board assembled using the DWM1001c chip.

Please see uploaded picture of the board.

It’s been flashed with the correct firmware and picked up by the Android app using bluetooth, and seems to be working perfectly with location data using both the Android App and also the DRTLS Web Manager. I’ve now switched off bluetooth and monitoring just using the DRTLS Web Manager.

My question is whenever I switch off Responsive Mode, I get no location data whatsoever no matter what I do. All the position readings show ‘NaN’.

I have 2 other tags on the same network which are the MDEK development boards and they all work fine with Responsive Mode off.

Does anyone know what could be the reason causing this?

Also, once you switch off Responsive Mode, there is no way to change any settings at all using the DRTLS Web Manager. It seems all communication with the chip seems to be lost. The only way to get it back up and running is to re-flash the chip with the original firmware to get back to the original default settings (with Responsive Mode on and Bluetooth on, etc).

Thanks in advance for your help.



In Responsive Mode I get constant location updates but when Responsive Mode is off I don’t even get a single update, just ‘NaN’.

Is this some configuration setting or a hardware issue? Could one of the pins of the DWM1001c be incorrectly set on the board?

With the DWM1001-DEV development boards, they all work perfectly with Responsive Mode off.

Any help really appreciated.

Thank you.


If someone could respond would really appreciate it as I’m pretty stuck on this and need to move forward with this.

Thank you so much.
