Dear all, I bought a Euro 12, small Elfin-EW10 RS232 to Wifi unit. I connected it to my RedBox FLARM and 12 V power. It works beautiful, I now have GPS, Hbar, Flarm via Wifi on my KOBO into LK8000. Simular to AL's bridge, only this Elfin box is ready made (and also small). Super easy!! |

Hi Robert, which Kobo are you using? and how do you avoid problem with Kobo wi-fi shutting down after a while? I have never managed to solve this problem, so have given up on wi-fi to Kobo.
More details, please :-) http://www.hi-flying.com/elfin-ew10-elfin-ew11 |

Nice, just a hint: You should check the power consumtion (current in mA, comparing 5V and 12V supply) of the Elfin? I'm afraid it has a simple LDO voltage regulator with a quite high power dissipation on 12V. AL |

looking on the device it shows 5W 5W/12V = 417mA |

Hi Bambuko, I use Kobo Aura One. When does wifi shut down? Did not have that problem.... Hi AlphaLima, Never checked that...Hope it is not a problem. Maybe go down to 5V? |

Sorry AlphaLima, Going down to 5V makes the current only higher, of course....

I use Clara HD, it was disconnecting wi-fi after 120 minutes. As I understand it - kobo don't have 'auto renew' of dhcp lease... Not easy to fuff around trying to re-connect it while flying :-( |

so if i understand it's depends of lease time configured in DHCP server, a common DHCP lease time is 24h, it could be insteresting to know what is lease time of your Elfin device... |

And what is the current value? |

I just ran KL8000 on my Kobo with wifi data feed via Elfin for 24 hours without any disconnect. Measuring of current value shows approximately 150 mA |
