Hi,
I am continuously reading data from the module.
AS per the TRM i understood that the module will reset if it is not getting enough time to reset the WDT.
So i wanted to confirm whether the module is getting resetted.
Thanks,
Likhitha

pls do not read data from the gauge more than once per sec. It is pointless as gauge doesn't make any updates more than once a second. There isn't a flag to indicate the watch dog reset, however, you will likely read out garbage data. That's the indication
thanks
