Following-up … if I add an exception handler and keep trying to connect, I get a bunch of different error numbers: Uncaught exception: -17168 Uncaught exception: -10368 Uncaught exception: -10368 Uncaught exception: -10368 Uncaught exception: -1 Uncaught exception: -32512 Uncaught exception: -29312 Uncaught exception: -16 Uncaught exception: -10368 Uncaught exception: -4480 Uncaught exception: -19840 Uncaught exception: -4480 Uncaught exception: -16912 Any advice on how / where to look those up? Cheers, Tim

@robert-hh Hi, sorry for my insistence on this topic. I 'm not able to use thread but I read about it and I think that it's better for my code if I use them . So do you know if is it possibile to use thread to read from two I2C through the code that I posted before? thank you.

@fedesilvi I recommend you try PySimpleGUI It's much easier to program a GUI in PySimpleGUI than PyGame. Do you have tkinter on your platform? You should be able to hook up your GUI to anything you want. To display your information, read the data using your code, then plot the data using a Matplotlib / Pyplot call. You can then display that graph in your GUI. There is extensive documentation on how to use it and there are several example programs posted the demonstrate hooking it up to Matplotlib.

Thanks for pointing this out, We've added it to our to do list.

hi @smbunn, The code was not modified. On a second thought, the altitude is just a simple function of the pressure, considering the same sea-level pressure. This is not ok, as the sea-level pressure varies in time, and from place to place. So, I would recommend, to use just the pressure, and if altitude is required, some arithmetics code has to be added, to get the right altitude. You could use some weather forecast service to obtain the accurate and real-time sea-level pressure.

@charly86 For OTA you just need appimg.bin, if the other two files are already loaded. The esptool.py command line for that would look like: esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 460800 write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x10000 appimg.bin

Can you please check your firmware version? import os os.uname()

Android and WiPy I' m working with this app from 2016 without problems. Remarks!! The used Android apps that I am using from the 2016 are the one that I find when I faced the same question that you have. Install(*) from Google Play Store the Mocha Telnet free application to open a micropython REPL session. To load drivers on WiPy boards, install AndFTP ( in my case) . Connect to WiFi WiPy network using www.wipy.io as password. In order to get the Python REPL, open MochaTelnet and from the menu select Telnet Settings and enter the IP 192.168.1.1 ( for WiPy 1.0) or IP 192.168.4.1 ( for WiPy 2.0 and LoPy) and the Telnet port number 23. Now return to main menu of Mocha Telnet an select Connect and at the login prompt in telnet terminal enter micro and at password prompt enter python. That is all. Federico Monaldi -July 10 2016

@jmarcelino Thank you for detailed answer

@robert-hh and @RobTuDelft thanks for your help, I am now up and programming! Perhaps a few of the issues I had could be better explained in the documentation, happy to provide some feedback if requested. Cheers!

I saw you efforts over at #112. Great work!

Maybe this can help you! http://forum.micropython.org/viewtopic.php?f=11&t=1228
