MiniVNA Tiny works as supposed with my Samsung Galaxy J5 over a standard OTG USB cable. No problems. Many thanks for this. I can't define the number of samples on the calibration though. I think it has a fixed number of cal points. (update 19/08/2016: I've noticed that there is some great discrepancy on the measurements between the Android Blue VNA and the desktop application vna/J 3.1.9. For example, the cable loss of a 0.5m RG58 at 144MHz is given as 0.6dB, while on the vna/J as 0.28dB, which is half of the BlueVNA calculation. I can, however, suspect that the limited cal points on the BlueVNA, compared with the 20000 cal points on the vna/J I used can be a reason for this difference.)
Thanks Dan for this wonderful app. I bought a miniVNA tiny because of this app. I did a quick Cable test with the 0.2m RG223/U cable with a known velocity factor of 0.66, but the results after a Run, kept showing length of cable is 0.15m. That is 25% difference. Not sure what did I not do right? I test the cable with the laptop software and that was accurately measured at 0.66 velocity factor, and length as 0.2m. Appreciate your advise
Best application for VNA It is the best application I've tried for my VNApro antenna analyzer. This Smartphone integration is better than the similar application on PC.
Used to work extremely well via bluetooth but now fails (unusable) with a lot of Java exceptions since phone upgraded to 6.0.1 - is this a known issue?
This is the app to use if you've got a miniVNA and an Android device. Works very well with my Vodafone tablet and OTG USB cable. Thanks Dan!
Changes in 0.9.6-3:
- full screen (immersive mode) with Android >= KitKat - navigation buttons are now hidden
- Bluetooth broken again in Android 6. Add back ACCESS_COARSE_LOCATION permission as this is required for Bluetooth discovery
- files saved with version < 0.9.5-1 are loaded incorrectly
Please send me a mail if you have any issue with the application before giving a low rating in Play Store. Thank you. Dan
