  You can use an FTP client (like FileZilla) to see and transfer files on the flash drive of your device via a static wifi (e.g. have your device and laptop connected to your home wifi) or by using your device as an access point (connect your laptop to the device wifi). https://docs.pycom.io/gettingstarted/programming/ftp

  @eric73 I am just creating the file and the first row, in my mind that's belongs to initialization. But correct me if not. Okay than I just use the basic file operations. Thank you! :)

  @priis In the first example you forgot to close the file. The with clause in the second example is doing that for you. So no need to close there. P.S.: When you enclose your code in lines with three backticks (```), then it is printed as such.

  @cmisztur If you just want a single call, then you could also use struct: self.i2c.writeto_mem(self.address, address, struct.pack(">H", data), addrsize=8 ) But no, I just was referring to a writeWord method: def writeWord(self,address,data): self.writeByte(address, (data >> 8) & 0xFF) self.writeByte(address + 1, data & 0xFF) That avoids the creating of two symbols & objects.

  @dan I understand that and get this error when I flash it, but I would also like it to link in Atom so I can build and run it right away without having to flash it.

  @alexpul But if it's only about not executing boot.py and main.py on boot, you can do similar with python scripts: from machine import reset def safe_boot.py() # create a special main.py and reset f= open("no_main.py", "w") f.write('''import os\nos.remove("no_main.py")\n''') f.close() reset() and then a specific boot.py, which checks for that special main.py: import machine import os try: f = open("no_main.py") f.close() machine.main("no_main.py") except OSError: # do the previous boot.py stuff here Or something similar in you regular boot.py and main.py, which just checks for the existence of a flag for bypassing.

  I just received a 2000mah and a 3000mah from Pimoroni in the UK. Great quality and not from China so they were here in 2 days. https://shop.pimoroni.com/products/lipo-battery-pack?variant=12704945864787

  @jcaron I have a WiPy 3. What do you recommend using for deep sleep? And for the handler interrupt, do you know how to integrate it while the device is sleeping?

  Hi @grideagle, Thank you for reporting that, I've reported it to GitBook. The current workaround is to use the "copy" button it the top right corner of the code section.

  @nick_w OK. b.t.w.: The test I tried to make did not give the epxected result, simply because TTN uses SF9BW125 in the RX2 window in the downlink for every data rate < 4. I could try with Loriot, but maybe later.

  @joseph I'm afraid I can't give you a timeline. The BT mesh is developed by Espressif, once they release it, we can start working on the implementation. We'll update the forum when we have a development version ready.
