Someone know an economic model of satellite (no gsm !) gps tracker whose data can be read with an app developed in B4a (of course still to be realized) ?
I agree with it.Finding an economic model of the milk could be a challenge.
This makes it sound like you're talking about satellite communications, eg, for global tracking of shipping containers (or ships) so that you're not constrained by having to be near a land-based and globally-compatible wireless phone network(s).2) a subscription (annual, monthly or other)
Then I'm guessing you're not married, because if you were, then you'd know that nothing is clear to everyone ;-)Yes. It seemed clear to me.
That is a lot clearer, although it'd help to know *why* the communication has to be by satellite, otherwise you'll still get a lot of why you can't just use the regular and cheap mobile phone network(s) queries.However, I specify that I would like a GPS satellite receiver that reads the coordinates and sends them to a satellite which sends them to a website.
Which communcation satellite for your uplink do you need ?@emerex
It seemed clear to me. However, I specify that I would like a GPS satellite receiver that reads the coordinates and sends them to a (another) satellite which sends them to a website.
The app (to developped in B4A) connects to the website, interrogates it and reads the coordinates.
Ok, you can use one of these cheap Wifi-Hotspots
Iridium GO! 9560 Satellite Terminal with Wi-Fi Hotspot
its very expensive and i think it can't behind metal, in case of anti car theft.This system is used to follow a car (and find it if they steal it) or to follow an animal in the savannah ;-)
cheap yes , but + Service costs each year for each device.
You might be on a winner with that USD $99 Spot Trace device, although the USD $225-275 per year service fee is still mildly eye-watering, as previously noted above.
It says movement/status reports are sent by "SMS text/email". Re: B4A, apparently receiving SMS discreetly in the background is not as easy as first seems (but is doable, especially if the Android device is dedicated to this role and doesn't have to handle other SMSs). Email should be ok, though - set up a free email account, and query it via so-easy-even-a-human-can-do-it POP3 or similar. Although there's the rub: SMS get sent to you, but email probably means you have to poll. Perhaps you'll be lucky and "SMS text/email" includes the option to do both.Did anyone in the forum use them to develop some apps in B4A?
