I am currently working on a way to get “battery charge” status. Without additional circuitry, I learned I could use Nordic nRF52’s successive approximation analog-to-digital converter (SAADC) driver to read the power being fed into the board, which indicates when the battery is running low, not its full charge, despite posts saying this was not possible with PANS as is. I still don’t know if it is possible, but seems plausible. There are other solutions with additional circuitry, but I digress.
Once each tag has this data, is there a way send it to the bridge? Can I create a custom tlv/shell command?
Based on the DWM1001 Firmware API Guide (page 119, table 5) and the Host API “dwm1001_tlv.h” file, I understand not all TLV command slots are being used, e.g. 0x09, 0x0D, 0x0E, 0x16. I am getting information from the tags with an ESP32 working as gateway reading from the shell of a bridge module, hence why I am asking about a way for the gateway to ask for this non-standard data from the tags.
