Gateway sends OK when I touch the Antenna
-
Hello
I am using W5100 with UNO. I am powering the W5100 from UNO ( I know this is not the perfect way but it worked for weeks ). Sometimes the gateway is initialized but it sends fail. I put my hands around the antenna and the gateway works OK.
Any explanation what da hell is that :) ?

problem doesn't happen using nrf without antenna. Maybe power problem ?

I had this problem and when i made a better ground connection from my voltage regulator to source ground it dissapeared... could be just a lucky call but...

Sounds like pa/lna module on max power. Have a read here: http://forum.mysensors.org/topic/1877/2-x-nrf24l01-pa-lna-with-rf24_pa_max/14
