Please make sure you do a lot of research, comparing not just the frequency but the channel information for your carrier against the PLS8 datasheet
I remember this came up before and the conclusion was that one carrier would* work with the European one, another would* work with the US, and another looked like it would work but closer inspection showed it was using a different channel or something and wouldn't work for either.
(*)"would work" meaning that all the technical parts seem to be there but like everything about this project, until someone's actually tried it we can't know for certain.
GSM 900 : Telstra, Optus & Vodafone
GSM 1800 : (Telstra, Optus & Vodafone all use this band for 4G instead)
UMTS 900 FDD8 : Optus, Vodafone
UMTS 1800 FDD3 : None
UMTS 2100 FDD1 : Telstra, Optus, Vodafone
LTE 800 FDD20: None
LTE 900 FDD8 : Telstra (a handful of sites, utilises spectrum previously used by 2G)
LTE 1800 FDD3 : Telstra, Optus, Vodafone
LTE 2100 FDD1 : Telstra (a handful of sites), Optus (Darwin, Tasmania)
LTE 2600 FDD7 : Optus, Telstra. (TPG have a license but have not announced plans for it.)
Looking at the store page again, it's kinda sad that the rumble and sensors are exclusive to the 4G versions.
Would've wanted them, but they obviously aren't worth the extra 100€ for those who don't have any use for 4G itself. Is that really cutting a bit off the production price or is this supposed to be a way to sell more 4G units?
I can live without them, sure, but I think this may affect the amount of applications supporting these later on.
I hope OpenStreetMaps gets ported to it soon, I love OSMAND (OpenStreetMapsAndroid) already.
He is taking a day off... he has been working nonstop the last weeks... just 1 day off... won't you allow that?It's just his silence on the issue is deafening.
Maybe date/time data from the GPS receiver can be used to synchronise the local RTC in Pyra. Wait, the Pyra has a RTC, right? I'm sick of the fakehwclock stuff in RPi.
Most NTP daemon can be configured for additional time sources. This can be GPS or similar (for example DCF77 is a reference time signal emitted from Germany).
OpenNTPD also has a cool feature that allow to get time from a HTTPS server you trust. The idea there is to get multiple source of information to make sure you're not getting a time from a malicious source. (NTP is not encrypted).
NTP deamon will typically not accept to modify the time if something looks odd (for example if your clock is set to 2016 but a remote server tells you you're in mid 2017!).
Acurate time is actually very important when you're administration a system and for system (HTTPS cert expiry dates...)
That's interesting, because ntpd on my Thinkpad X200 with broken RTC (thanks to libreboot I assume) routinely switches to current time after running for a few hours in 1970, after connecting to the internet …
I'd also like to know the problems with manually setting the time (will be inaccurate by about 20s usually) and certificate expiry dates … I guess I must have not seen the 30-second-validity certificates you have …
The benefit is, that there simply won't be any Pyra without enough pre-orders. I think we needed around 500 minimum to make it happen and this point has barely been reached.Indeed, and this is why I haven't pre-ordered. There's no benefit to it (it's not any cheaper) other than getting a unit before there's any real software available for it
Indeed, and this is why I haven't pre-ordered. There's no benefit to it (it's not any cheaper) other than getting a unit before there's any real software available for it - by which I mean software that has been ported with the Pyra in mind, as opposed to the usual "It builds, ship it" that we had with the Pandora in the early years. And of course, there's the very real possibility that we won't actually get one for a long time anyway. Having been burned by the Pandora in that regard, I'm hanging onto my cash until there is stock to buy.
Ditto here. I did not pre-pre-order, as it both lasted very short AND there were enough fanboi's stepping up. But I did preorder now to "make it happen" (sold my kindney amd stuff), as we are now talking big figures to start production...it would never happen
