I got mine yesterday, but the micro-usb connector on my Nexus 5 is backwards, so i can only take thelfies... I actually got a micro-usb extension cable, but for some reason it does not work (the Flir One app does not recognize the device if it's plugged in via the cable). However if I use the micro-usb extension cable together with my charger cable and use it to connect the phone to the pc, i can even transfer data, so the data lines seem to be ok. What else could be wrong. Is there something i need to consider when buying a cable?
Yes, it must be an OTG-compliant extension cable.
In such cables, the ID pin is shorted to GND to let the phone know that it should be a host instead of a device. But most cables out there leave it unconnected internally.
You can carefully insert a small strand of wire across the contacts and get it working.
Here's a short video taken with my F1 G2 for iOS if anyone is interested in seeing the frame rate that the iOS version is getting and wish to compare with their android's frame rate.

Thanks, I'll try that. But I don't understand how this is necessary, because when I plug it in directly, without any cable, then the pins are not shorted either (or are they shorted internally in the flir one? but then a straight cable should work as well?)
Because the cable leaves the ID pin unconnected. Standard USB only has 4pins, MicroUSB has 5 (5th pin is ID). Inside the FLIR One ID is shorted to ground, but if your extension cable doesn't connect the ID pin to the FLIR One, then the phone can't detect that it's shorted.
Regarding the resolution, I'm pretty sure it's 160x120 thermal resolution. I took a picture of some nichrome wire and played with the ranges in Flir Tools to bring out the details:
Dividing the number of pixels/step by the vertical resolution gives 160px.

But can you post the RAW values from your nichrome wire?
I just had a look at t9.png after doing the byteswap/auto-level from the other post.
It looks like the sensor is only 128*96
There are 19 points over a 47 pixel range giving a physical pixel -> image pixel ratio of 2.47.
Dividing the image resolution by 2.5 gives 128x96.

one square = one sensor pixel of Flir Exx
the result is really sharp (thanks to good optics of the Flir Exx)
Can MSX not be turned off? It seems like more of an annoyance than anything else, because I would use a Flir One for macro-type imaging than anything else.
Nathan,
Can you see the GPS location with your IOS Flir Tools?
On the Android Flir Tools Mobile I see my GPS location with the wrong E/W designation ie. it's placing me somewhere in China.
The samples that came with the Flir App show all E Longitude, and I'm wondering if there is a bug in the Flir One Android app, or Flir Tools Mobile.
I read out the exif data with exiftools and I think there may be some new/changed Tags in the Flir One files.
GPS tags from the exif data from my Flir One image with exiftool:
GPS Version ID : 2.2.0.0
GPS Latitude Ref : North
GPS Longitude Ref : West
GPS Altitude Ref : Above Sea Level
GPS Map Datum : WGS84
GPS Latitude : 38 deg 53' xx.yy" N
Camera Software : 1.0.0
sample images that came with the Flir One app, I see the following GPS tags:
GPS Version ID : 2.2.0.0
GPS Latitude Ref : North
GPS Longitude Ref : East
GPS Altitude Ref : Above Sea Level
GPS Map Datum : WGS84
GPS Latitude : 59 deg 27' 19.02" N
GPS Longitude : 18 deg 7' 50.04" E
GPS Position : 59 deg 27' 19.02" N, 18 deg 7' 50.04" E
