Yes did that but it couldn't extract the new program to the sd card. Reverted to the old version which installed correctly but unfortunately Skydemon says cant connect to butterfly unit. Will have to investigate
   

Sorted It had lost the Licence Key..

Same problem when it tries to write to file system.. Done full formats etc with no luck. Have reverted to previous version and that seems oK

General Discussion / ARF alternatives.. XBee 868 ?

« on: November 05, 2015, 04:43:41 pm »

Is it possible to configure the XBEE 868 Pro to serve instead of the ARF board. With the 350mw power that should give suitable range probably at least 20km even with a 1/4 wave vertical air/air.

Pressed the configure button and entered the hex code but it had lost the data connection by that time.
I have only managed to get to that screen once.
I think the dongle is In the bottom right one if you look at it from the usb side.

It's an iPad mini.
Everything connects to the pilot aware wifi. Tried on  pc android and ipad.
Pc indicates data being sent and received when interrogated.
Dongle indicates data being sent or received with it's flashing light.

Nothing normally logs onto the 192 address.
Except once! Kept retrying and got a table screen of pilots ware perameters..
Then got the login screen
Entered passcode and it came back with not able to connect to server
Frustrating.
Corrupted data?

After installing and running the boot up sequence till it asks for the license key I cannot enter it as it repeats the message License fail for host every second. I cant interrupt it.
Has the timeout reset to zero or something?
Have reinstalled software and it does exactly the same..

Help please,

True 5 miles Is possible with around 90mw I think the ARF is capable of. What we need is a Rock Solid signal even when theres line of sight issues cockpit positioning etc.

Theres only a 25khz section of the band that permits 500mw can someone confirm the ARF is transmiting in that section.

Given 400+ mw and a half decent antenna that negates the need for decent ground planes unless you have a metal aircraft and want to start cutting holes in it... (not forgetting Mod Status) I believe 5miles minimum certainty contact is achievable.

Assuming licence restrictions are OK we need a bolt on narrow band amplifier accepting the input of the ARF module or even the XRF which would be cheaper. Shouldnt be too difficult I wouldn't have thought except for cooling issues if running a continuous amp.

Another thought is how good is the ARF receiver would a decent antenna and a preamp work or would we swamp the ARF RX.

Light bulb has just gone off..... must contact a friend who used to work in this field designing kit for the mobile phone network and P2P communication systems....

868Mhz realistic requirements............

Realistically we require 868 to establish rock solid 2 way contact air to air at a distance of 5 miles anything more is a bonus.

ADS-B units are designed as Air-Ground even the small units run 130Watts into a compromise antenna to give a design range of 150miles.

Is it possible to achieve this using the 868 band? I believe it probably is but we would need to utilize the maximum permitted power output in the High 868 500mw and use a descent antenna eg. a v- rabbit or at least a dipole for those that have ground plane problems...

So are these parameters achievable and is it permitted?
