Issues with experimental_ble_app_uart

[Ron]

I'm new to nordic. I am using Nordic DK (PCA 10028) and was able to flash the heart rate example on to the board and see it on my iOS device. I'm trying to test the uart sample but that doesn't seem to work.

I have pin 9 & 11 connected to a separate boards TX & RX. That board is connected to a PC via USB to UART cable and running hyperterminal with the following uart settings

baud rate: 38400 data bits: 8 Parity: none Stop bits: 1 Flow control: hardware

Now I use jlink to load s110 bin as well as the output bin when building the example project. I don't see LED1 turn on as it's supposed to. Rightfully so, I don't see it appear on my iOS device. Is there something I'm missing?

I'm not sure you are aware, but you don't need to connect the pins, you can use J-Link CDC to have UART between PC and the nRF51.

Regarding the experimental_ble_app_uart, please have a look at this.

Thanks. My problem seems to be that the application on the board is not running. I'm expecting LED1 to be on, but it's not. Nor am I able to discover the device. I was working off of a Mac. Switched to Windows and downloaded J-Link for windows and still don't see it behave like expected.

I did look at the link and removed PCA_10001 from the makefile.

With the new nRF51 DK you need to connect the UART to a terminal. I'm not exactly sure why, but I suspect there have been changes in regards to flow control.
