Additional sensors (magnetic field, gyroscope)

nauvpp

Hi,
The Ubuntu Touch OTA-19 Release states that Halium 5.1/7.1 devices have access to magnetic field and gyroscope sensors.
I remembered @Flohack demoing rough compass support (with erratic values) on a device (don't know which one) in a Q&A session some months ago.
On [PRO5] "SensorStatus" does not display any value but "test_sensors" seems to show lots of sensors [1].
I'd like to dig this out... I searched for "sensor" throughout the forum, read couple of posts, but no clue how to move forward... Does some of you have hints or docs to read ?
BR,
Nauvpp

Unfortunately the Meizu Pro 5 is not a Halium device, but a legacy port which we cannot rebuild (closed sources), so we cannot inject the missing sensor glue code. Its the same on the BQs...

Hi @nauvpp
As it turns out it's device specific, I moved the thread to the corresponding subforum.

@flohack
Problem with accessing sources is on Canonical side or Meizu/BQ one ?

nauvpp

@flohack ok thank you for the clarification

Legacy means closed source, so very few chance to have additional sensors supported. Moreover, these devices are becoming ”old„ (as I do )
Halium means additional sensors may be supported, depending on Halium availability

How to consider a GSI device? Is it halium too?

@applee thanks! Status changed to “topic„

But old is not dead.
I can assure you that my MX4 is still kicking a**es

Exactly. It's good for the planet to keep using existing devices, instead of getting new ones every two years and creating tons of e-waste!

nauvpp

@keneda Sure it does !
I also own a MX4 (Ubuntu edition). I can't make the GPS to work since a while. It can't fix my position even after let it try for 1 hour...

nauvpp

@moem I totally agree and that's a benefit among many other with UBp. I learned with this post that “legacy” devices will likely not have such sensors working. IMHO, that's a drawback to me cause compass is so convenient combined to GPS when navigating by foot

Get yourself a Pebble smartwatch (yes, that is legacy too)... you can connect it with your UT phone and it's a compass too! ️

@flohack one more question I you don't mind: I also own a N5 hammerhead, is it legacy or halium 5.1?
Thank you

AppLee

@nauvpp
IIRC the official port is a legacy one.
There is also a work in progress about an halium 7.1 port.

@applee thanks
