Can't change tdoa kit tag data rate

Wireless Connectivity Ultra-Wideband
1

I want to change the data rate of the TDOA kit (TTK1000) tags to 110 kbps. I connect to my PC through Teraterm and modify, but I get “error function” as response. I can change between 850kbps and 6810kbps, but as soon as I try 110kbps I get the error. Any reasons why?

Hi Pema,

you are right, currently, their is a little bug in the 110k setting， but you could self fix it,
1, download the tdoa source code from : https://www.decawave.com/wp-content/uploads/2019/02/DWM1001_TDoA_Tag_Ex.zip;
2, in the file cmd_fn.c:
if(tmp>0)
{
pbss->dwt_config.dataRate = (uint8_t)(tmp);
ret = CMD_FN_RET_OK;
}

changed:
if(tmp>=0)
{
pbss->dwt_config.dataRate = (uint8_t)(tmp);
ret = CMD_FN_RET_OK;
}

3,then rebuild the project and download the hex to tag , you will be able to make it work correctly.
