Re: [time-nuts] Ublox timepulse

Hi Christophe, after having a quick look at the Ublox Protocol Spec. and testing on a M8T it seems the only solution will incorporate some parsing of messages. The UBX-CFG-TP5 message allows for a user delay but only about +-2s and an alignment to top of second. You could however parse the

Hi I suspect that even with setting the timepulse to 60 seconds and aligning it, you still will be routinely parsing the serial just to be sure “all is well”. There are always random things that come along and mess this or that up ….. Bob > On Feb 4, 2020, at 10:11 AM, Tim Shoppa wrote: > >

freqPeriod is in microseconds up to 2^32 so you ought to be able to set it to 60,000,000 and get one pulse a minute. If you set alignToTow will align it to the top of second but not top of minute so you'd have to parse the UTC timestamp and use it to "start" the 60 second cycle at the correct

Hi, I need a sync pulse every minute at start of minute, aligned with UTC time (let's not discuss what UTC time really is :-)). Any quick assessment whether uBlox TIMEPULSE out can do this? It does not seem to be a problem to generate a pulse every minute based on UBX-CFG-TP5, but how can
