Better explanation needed for the use of input 1 for a pairing button

[rmtucker]

Still waiting on my CC2530 and programmer arriving but having trouble with firmware config: I wish to have 2 DS18B20 sensors,1 on output 1,and 1 on output 2 as pic But then if i try to add input 1 external wake up it gives the following error I just want to add an external button for pairing (hold for 10 secs) Or should it just be set as GPIO and switch?

@rmtucker You cannot combine DS18B20 and "External wakeup" on the same line #1 (endpoint #1). It is the internal limitation. You can shift DS18B20 to Output 2 & 3.

I understand thank you But is external wakeup the correct choice for a pairing button,or should it be just as switch on gpio?

The External wakeup button on Input 1 can also work as a paring button.
