DWM1001C UART TLV sometimes not response for about 10+ seconds

Hi,

I’m communicating with DWM1001C tag node (running PANS firmware) using UART TLV. The command dwm_status_get is sent to get loc_data bit then if this bit is 1, the command dwm_loc_get is sent to get location data. This routine is running with 10 Hz rate.

While running this routine, I notice that sometimes the tag does not response the dwm_status_get command for about 12-14 seconds but after that it comes back to response. Are there any issue with my approach or the module itself and how can I handle this problem correctly.

Thank you

Hi @kanpinyo
there is a known issue that cause module hangup while it is pooled for new location too often. Please use IRQ pin for determining if new position is available.

Hi @leapslabs,

Thanks for the clarification. By the way, will the module always come back after constant 10 seconds when the hang occurs? Does this relate to the watchdog?

Thank you

Hi @kanpinyo
yes, there is 10s watchdog.
