Reading this up and down a couple of times. But still cannot figure out if V_BCKP is connected to the L76 GPS or not? Trying to use go_to_sleep(gps=True) but it still takes 30+ seconds to get a GPS fix after waking up. Straight up, do I need to solder a bridge on the unpopulated component or not?

Hey, I sit here an i trye to read the temparature with the LIS2HH12 but it dosent works. What did you do that the LIS2HH12 give the Temperaturen out? I Hope so you see this post. Best wishes

Thanks for the advices. The FTDI board is set to use 3.3V. On my FTDI I soldered an additional pin to the 5V, and connected that to the LoPy 5V, Connected the FTDI to LoPy with GND-GND, RX-TX and TX-RX. Connected the "G23", this is the 4th pin next to the TX/RX on the LoPy, to GND. This G23 = P2 = GPIO0, see https://forum.pycom.io/assets/uploads/files/1490693421335-index.jpeg Now the download worked fine using the PyCom Firmware Update tool.

@livius ok. Thanks. I can see the method used in that source. DOCS for the file transfer API would be really useful too but this will get me started. Thanks
