LoPy + GPS receiver on The Things Networks
-
If you have a LoPy node that is moving around, knowing where it is, can be very useful. Think containers or cars moving around. GPS receivers can be expensive or very cheap. I used a cheap one from China to connect to the LoPy.
Like before I shared the code online and created a write-up on my blog.
I hope it is useful to others also.p.s. Alex will be doing a live broadcast about the Pytrack and GPS this week. It's a bit more expensive, but also has a 3 axis 12-bit accelerometer and combines everything in a neat small package.
(fixed the link to the github repository, thanks Rob!)

Thanks for the link on aliexpress for NEO6MV2
Is this real link to seller or you buy it from different place?
I buy it normally for 60% higher price in my country.think about people first, then computers

@livius
there are often recycled modules, you can even get a similar board for $3.78 ( inc free shipping, at least to UK) https://www.aliexpress.com/item/GY-NEO6MV2-NEO-6M-GPS-Module-NEO6MV2-with-Flight-Control-EEPROM-MWC-APM2-5-large-antenna/32654502054.html -
@livius This was the link to the actual reseller that I bought it from. The one that Jose links to is indeed even cheaper, but the text "Attention: the chip is old" kind of puts me off on that one. :) (although they just mean the chip has been used)
Would I buy them if I was building a sensor network for a big company? Probably not. For small projects like this, for me they are cheap enough to take the chance. -
@jmarcelino @PiAir
I am only asking if someone buy something from aliexpress and this work ;-)
I know that we can buy it even cheaper.
But i bookmark any link with working models which someone buy from china.Sometimes whole module parts toogether have bigger priority then "quality".
But i always try to minimize risk then. -
@livius
I think you can safely buy from Aliexpress, it's easy to make a claim if something doesn't work and sellers are usually OK with refunding. I never had any problems there and I spend quite a bit!Should we start a "Bargains" thread here with "companion" stuff like ADCs, sensors, tools, components like there is in the TTN forums? I personally have a list about 100+ favourite Ali sellers and an even longer one with interesting products :-)
-
@jmarcelino Don't know if there is a need to duplicate that TTN thread. Maybe just link to it? :)
I also never had any real problems with sellers, sometimes it takes a while, one or two refunds requested (and received) so far after (too) many orders. -
@PiAir
I use near to always same gps model and it is quite accurate
but not always. Have someone other gps more accurate in near price
sample
this is data from 5 hour testing gps on the window. I am in yellow point and not moving.
UPDATE
This is only area - but 94% points are really near to yellow point -
@jmarcelino
I think that we can create something more accurate - on that link all is mixed up
Adding not one topic only new menu group e.g.:->Where to buy:
--------->Sensors
------------------>I2C
------------------>analog
--------->switches
--------->Bateries
--------->antennas
--------->simple electronics
--------->boxor only limit it to interesting sensors.
But as always on such topic we can end with spam with adverts
not real used items by users :(
