Newby Question: compiler warnings and capacitor size on NRF+

@sundberg84 said:

I primary use 4,7uF and are tested higher and two caps paralell on my gateway atm.

I can ACK this:
On the Gateway i need 2 caps: 100uF and 4.7uF. without the 100uF cap I had some really strange behavior when starting the gateway until the communication got established same (random) times
At the nodes 4.7uF is sufficent.

Thanks a lot for your answers. I have installed the caps and both the node and gateway are initiated every time flawless but they refuse to communicate to each other. The modules are recognized as being '+' versions using the GetStated sketch from the RF24library. Tried to setup both uno's in different ways (pingpong; serial gateway and sensor) but none of the combinations shows any way of communication between the two boards. I have been struggling for three days now; I am out of ideas and I am afraid it's a problem with the nRF modules (see this link also ) . I will try to order some new ones.....

How far from eachother do you have the nodes?

[DutchMurk]

@sundberg84 : in the same room. One on the serial monitor, one in an external power supply

[DutchMurk]

After a steep learning curve I found out that one of my UNO clones was not able to receive messages in any way. I have now made a sensor based on a pro mini which works fine with a serial gateway. The only problems I still encounter is that the node-ID is not assigned automatically but I solved it by defining it in the sketch. @sundberg84 : I saw a different post of you for the Easy/Newbie PCB for MySensors. It looks very tempting to start using them !

openhab does not manage the IDs. it's simply not implemented on the openhab side

@dakky

Do it have to be electrolyte cap or can it be SMD cap?

[mfalkvidd]

@flopp smd is fine

@mfalkvidd
Thanks. Make it much easier to make a small-size-project

[flopp]

Can the SMD cap be like this?

I have tried and it works but isn't to small?
