@livius Solved, but then, having this issue:

<LIS2HH12 object at 3ffe7690>                                                                               
<L76GNSS object at 3ffe7680>

@papasmurph please submit a pull request will all your changes, and we will take as much as possible from it. Thanks for contributing :-)

Hi @papasmurph, please do make a pull request, am always happy to consider improvements - this has been very much an out the door release as we've been pushing to get a minimum working library out the door for people to use!

[papasmurph]

@bucknall I don't use Github for other than complaining about things, so there's certainly some learning curve. It would have been much easier for me to just "zip" the things I changed and send it somehow. I hope that works. Otherwise this might take a few days due to other responsibilities.

[bucknall]

Hi @papasmurph, feel free to send it to me (alex@pycom.io) and I'll look into implementing it for you :)

What issue? please describe it more..

dfu-util is not working somehow on my linux client.

dfu-util 0.8

What is going wrong?

[papasmurph]

@gertjanvanhethof Did you do the "press button before plugging in USB" bit?

What @papasmurph said and you probably need to be root

I am not sure what the Pysense does, but it is not what I would expect. I am running the following code multiple times within a minute or so. Maybe someone could explain what the results mean. I have a BME280 here and it reports 24.7 C and a humidity of 47.06%. Temperature jumps between 31 and 4800, humidity between 48 and 2800. Pressure.temp is pretty stable but 5C off and why does the pressure sensor not Report pressure?. Ambient returns two values for Lux, both of them impossible during daylight.

from pysense import Pysense
from SI7006A20 import SI7006A20
from LTR329ALS01 import LTR329ALS01
from MPL3115A2 import MPL3115A2


py = Pysense()
pressure = MPL3115A2(py)
tempHum = SI7006A20(py)
ambientLight = LTR329ALS01(py)

print (tempHum.humidity())
print (tempHum.temp('C'))
print (pressure.temp())
print (ambientLight.lux())

I got the following results

>>>
2693.687
31.87222
30.5 
(21, 27)  

>>>
48.81235

[papasmurph]

@jmarcelino That might even be needed on a Mac.

[papasmurph]

@Camot I've sent Alex new code that should work better (no guarantees though), but temperature is off due to heating from the board. I changed the code to measure pressure instead of altitude.

[bucknall]

@Camot I'm investigating this today and will likely merge @papasmurph's code when I get a chance to review the changes

[Pajarraco]

Maybe its a fool question, but when I try to download the new version 1.0.0 here: https://docs.pycom.io/pycom_esp32/pycom_esp32/toolsandfeatures.html#updating-pysense-and-pytrack-firmware

The download file has the name pytrack/pysense_0.0.2.dfu and not 1.0.0.dfu or something like that.

By the way, I just got working the accelerometer in both pytrack and pysenses, but the humidity, temperature, or glonass sensors don't work :(. May i wait some days more or is something that I have done wrong?

Edit: well, seems that i misunderstood the concept of the version of the DFU and the version of the Pytrack/Pysense libraries...
Futhermore, in the case of the Pysense, i forgot to print the values...Thanks to @Camot I could obtain some values but indeed, they are a bit unstable. About the Pytrack,I cannot get the coords. I modified the read function in order to print what it reads and well, it doesn't appear the word GNGLL so it is stuck in an infinite loop. Any ideas?

[livius]

@Pajarraco
Where do you have pytrack inside building? On it work for me.

[Pajarraco]

@livius I was running next to a window and it didnt work for me. Now I have just peeped the Pytrack outside with one hand and running the script and I could obtain the coords outside and inside. A little strange but well, it works :)

[gertjanvanhethof]

@papasmurph @jmarcelino Yes, I pressed the button and did a sudo call.
Atom pymakr plugin is working fine so I'am able to communicate with the board. What could be wrong?

[papasmurph]

@gertjanvanhethof Pressed the button and then inserted USB? Just checking :).

[gertjanvanhethof]

@papasmurph Yes, pressed button on the pysense board and then inserting the USB.
No problem to ask. You never now.
Could it be a problem because I'am using linux from in virtualbox.
As said Atom is working fine so port is working. But probably it takes more time to setup the serial connection through USB in that case, so causing the problem?
Make that sense?

[Pajarraco]

@gertjanvanhethof Are you releasing the buttom 1 s once you plug in the USB wire? Maybe you can try instead of dfu-util, dfu-util-stable, and try to add --device (the device id when it cannot be opened). I think another option to see if it detects the Dfu devices is to show a list with the option -l
