Newby Question: compiler warnings and capacitor size on NRF+

[sundberg84]

Hi!

1. I primary use 4,7uF and are tested higher and two caps paralell on my gateway atm.
2. I dont know but when i struggle with this, i mostly just completely reinstall the lib from the homepage.

Those are just warnings, and from what I see, there is no problem in them (they've changed some naming conventions in the core files, that we apparently haven't migrated to our hardware addons. But they gracefully change them to the right thing, together with the warning).

Will probably need a minor change in the mysensors hardware definition files.. But I don't know if that will come in to master branch now..

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?
