I have a peripheral device based on the nRF51822, s130 and SDK 11.0.0. It's designed to only ever have one central device to which it's bonded. Out of the box, without a bond...
Hello.
I have a question.
I want to use UART without flow control.
In this case, I don't know what to set rts_pin_no and cts_pin_no of app_uart_comm_params_t.
Please...

Hi all:
I refer the "IoT_SDK_step_by_step.pdf" to setup my raspberry_pi ,then I can successfully ping the DK_board from raspberry_pi.
my question is , I can't ping the...
Hi everyone!!
I've gotten the ipv6_coap_server example to run on the nRF51-DK,and I use raspberry pi as gateway and I can got the bt0 interface after connecting to the...
I would like to add LIN-bus to a project of mine.
The hardware part is easy, connect a LIN interface ASIC to the UART of the nRF5x.
But writing my own LIN-bus SW driver...
Hello World!
I am trying to interface an LCD with nrf51-DK. I basically need to send 3 signals - SCLK, MOSI and SS to the LCD. I have modified the spi_master example from...
I am working with a sensor which has a programmable configuration register. After changing this register, I have to reboot the sensor. To do this, I need to temporarily suspend...
Hi, I try to send data through SPIM to my panel(Sharp Memory LCM), and I success get the picture (only part of the picture).
The reason why is that function can only...
I have migrated to SDK 9.0 primarily to take advantage of some of the Advertising Mode functionality in Device Manager. While I was still in SDK 8.1, I had implemented functionality...
