Wireless transciever with external antenne does not work.
-
Hello all,
Can someone help me with the following.
I have succesfully made a serial gateway and a servo actuator. I want to use the tranciever with external antenne. When I use the one without the external antenna:

Everything is working fine.When I hook up the shield with external antenne , it doesn't work.

Also the Decoupling-Capacitor is installed , but as soon as I switch the tranciever shield , from the build in antenna to external antenna , no joy.I have tried several Arduino nano's

When I use my Arduino uno, it works , when I connect the external antenna shield directly on 3.3v or with stepdown on 5v or on external powersource with the stepdown regulator.
Anyone has an idea why I can not get it to work on the nano's?
thanks,

Try with some different sizes/variant for the decoupling capacitor.
Try some other regulator/powersource.

okidoki, will do ,
