Blink LED with nRF51822 Developer Kit / Bluetooth Smart Beacon Kit

[random]

Is there anyway to get a light to blink using only the PCB antenna module?

Also, is there anyway to blink a light using only the Bluetooth Smart Beacon chip?

I have the PCA10006, which has the nRF51422 but I assume it should be the same for you. Check the schematics for your board to be sure you are connecting everything to the right ports. They should be listed as hardware files in your "my downloads" page.

On my board, P2.02 is connected to VCC with 3.6v, P2.06 to GND, with that the chip now powers up and is visible to the Segger debugger. Then on P2.31 and 32 (or fifth position up->down) I connect the LEDs.

P1. positions 30 and 32 (or 5 and 6 counting up on the same row) have TX/RX which is connected to a UART module with an FTDI chip on it.

The board in the picture is running the S110 experimental BLE/UART app, when I connect from the Android app the green LED turns on and the red turns off.

Thank you for your answer! It's been extremely helpful and I think I'm almost there. Could you post a large picture of your hardware setup? The UART chip and everything in the pic??

Also, what example did you say you were running? I don't see a BLE/UART in the s110 folder (including in the experimental folder of Board/s110).

I added a second picture to my answer.

The BLE UART demo is in the nrf51822 folder, but it works with the nrf51422.

Did you have to modify the code at all? I was able to get the hardware setup and install fine but I'm not able to see it in the Master Control Panel or on my iOS device. Any suggestions??

I don't understand how you specify the LED pin. All I see is LED_0 and LED_1. How is that specifying P2.31??
