Hi! I am working on a project that uses the Multilink example. On the client (nRF51422 w. SD 120) my program crashes and starts the main loop again after a few seconds. I...
Hi,
I'm developing a device that will be powered by two AAA alkaline batteries.
Since the operating voltage of nRF51822 is 1.8 to 3.6V I was considering to connect them...
Hi,
the example ble_app_uart_s132 from the SDK 0.9.2 is not longer working with the new release of S132 ( s132_nrf52_2.0.0-7.alpha). I had to go back to s132_nrf52_1.0...
My setups are:
RBL BLE Nano
nRF51_SDK_9.0.0_2e23562
Keil uVision V4.74.0.22 or gcc-arm-none-eabi-4_8-2014q2-20140609-win32

First, I program softdevice and dual bank bootloader by nRFgoStudio. After that it is possible to program my application...
Hi all,
first of all thank you for such a great knowledge base and community exchange.
I am pretty new in the development for nrf51822 devices.
I managed to run the...

I'm using the s130 SoftDevice on the nRF51 dongle and writing a PC app in python. How can I declare an int8_t in python for use in the sd_ble_gap_rssi_get function? The function...
Hello there, I am already guessing that by the question alone it seems like what i'm asking is silly or wrong but I have no formal education here so I will need some help...
Hey guys,
I'm building a remote control (similar to TV remote) and I'm using nRF51. I am trying to figure out optimal connection parameters so the battery would last as...
I am using nRF51 SDK v10.0.0 and running simple_uart application on nRF51822 Evaluation Kit(PCA10001).
Added CFLAG += -DBOARD_PCA10001.
