It has 12 pins that need to be connected to work. I've had it all working on the UNO and mapped those pins to the Flora that I'm using. I've soldered SPI pins and connected all cables to where they need to fit on the Flora, then loaded the same code that worked on the Uno (see code below), but unfortunately it doesn't work and the receiving client doesn't receive the ping.
As you can see in the photo below, there are a few LED lights on the Flora - I have a fixed red light as well as blinking yellow light plus the green power light. I'm mainly concerned of the fixed red light - I searched online and couldn't find what this actually means.

It might be due to one (or more) of the connections that I mapped incorrectly or that there is something wrong with the code. The mapping is based on the table below (I got a lot of help from the admin of this forum to build this table). The table includes the wiring for the UNO and the Flora. The connections for the UNO worked perfectly according to this diagram: http://blog.zakkemble.co.uk/wp-content/uploads/2013/01/nrf905_bb.png. Note I kept all resistors in place. Maybe that's the issue?

Regarding the code, it seems that I can't change the pin numbers as some of them have changed from the UNO to Flora (e.g. pin 8 on UNO is now D12 on Flora). However in the code the pin numbers are all commented so I can't change them. I'm just a beginner with Arduino and I'm not sure where I can actually change it. Is it somewhere in the libraries?
Any help would be greatly appreciated!!
Thanks :-)
