The f.close() call should be enough to get the file fully written.

Wow! the cache makes quite a difference!

I should say that I didn't find that number anywhere on the wipy.io website; just pictures of the WiPy plugged into a breadboard. @danicampora, maybe you could point to that spec somewhere in the documentation? Thanks for the remark, we are preparing a hardware manual that will also show the dimens...

The only down-side is that they do not fit into 2.5mm spaced holes (they're 3.5mm spaced) - but they do fit in most perf/proto-board if you rotate them diagonally (see photo above).

They won't

Does MicroPython provide things like socket.ioctl() and socket.setsockopt() for controlling socket behaviour (and implement them for WiPy)? So could I do sniffing / promiscuous listening?

Yes, both are implemented.

Hello theBellHead, This can be done just using standard Python sockets calls, for example: import select, socket import pyb from network import WLAN s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM) s.bind(('', '8889')) s.setblocking(False) # then, to receive something result = select.select([s],...

I did some testing and also checked the CC3200 datasheet again. Active (WiFi Disable mode) MCU @ 80MHz The current only drops 800uA, therefore I don't think that the benefit is worth the hassle. So instead of 14mA it consumes 13.2. The CC3200 Network Processor was designed from the ground up to be u...

Remark on the previous post:

The issue with file operations while WiFi is disabled only affects /flash file system. The SD card has no issues with this.

Hi JimTal001, 1. Why is the power requirement so high in suspended WiFi AP mode as compared to suspended WiFi Station mode? Because an access point needs to fulfill certain requirements like sending beacons, keeping the receiver ON all the time, etc. This needs to be done like this in order to be fu...

Hello JimTal001, We will add detailed tech specs with this info to our website. In the mean time, here they are: Active (WiFi Station mode) MCU @ 80MHz ---> 14mA Active (WiFi AP mode) MCU @ 80MHz ---> 45mA Suspended (WiFi Station mode) ---------------> 850uA Suspended (WiFi AP mode) ----------------...
