I have been working with the DWM1000 modules on my own custom board and I am having a bit of an issue connecting a tag and anchor in a TWR scheme. I am fairly confident my network configurations are correct across both devices but this is one possibility that I haven’t ruled out. My anchor is essentially going into receive mode after setting up the network and listening for a blink message from a tag.
One thing I am noticing is that my anchor is reporting a temperature of 178C whereas my tag is reporting a temp of 34C. I am following table 14 in the DW1000 user manual for read temp and voltage sensors. The voltage reading is typically 3.32V
I was wondering if anyone has ever had any issues with DWM1000 modules getting this hot.
Also I was wondering, what is the internal temperature sensor near in terms of the internal circuitry of the chip? What components in the chip would be getting this hot?
I have replaced the DWM1000 module on the anchor, and the exact same thing happened when I loaded the anchor code onto it. I loaded the anchor code onto my tag hardware, because it’s the exact same hardware, and it started reported high temperatures as well. So I am trying to narrow down my issue between hardware layout and software configuration. I’d be happy to share more info if it would be helpful.
Thanks for any insight!
