UART on DevBoard vs. Reference Beacon

[james.eberhardt]

I'm trying to send data over UART... started off using the examples from the SDK.

When I run the code on the dev board, I can get it working. When I load the code onto the reference beacon, it's not working. I'm sending the data to a Raspberry Pi and can successfully read it coming from the dev board, but not the reference beacon; from the reference beacon, I get nothing at all.

From the dev board, I'm only connecting 2 pins - GND and Pin 9 (TX_PIN_NUMBER), then on the Raspberry Pi, I am connecting those 2 pins to GND and the RX Pin. The baud is 38400. Everything's good until I try the same thing on the reference beacon. I'm trying to touch to test point 9.

Is there any reason why UART would work on the dev board and not work on the reference beacon?

Thanks.

Are you sure the code is not running into a fault and resetting or stopping (devzone.nordicsemi.com/.../) Are you using the boards file for PCA20006 (beacon)? If not the buttons and leds will have the wrong pin definitions.
