Hi,
I have two CPU in our product. (STM32F2 and Nordic nrf51422).
I use serialization function to link those two CPU(refer to ble_s110_serialization sample)
But I find...
So I have a remote, a central, and it's connected to my peripheral.
The remote is based on the multilink example.

I want to press a button on my central and...
Hi, i'm wondering if it's possible to make a GPIO pin trigger different tasks when it is externally driven from low to high, and high to low.
I'm trying to stop an RTC...
I would like to NRF51822 bluetooth test.
It has NRF51822 eval-kit 2EA.
1EA is a Central (dongle role), 1EA want to test the bluetooth interlock with Peripheral.
What should...
I hope this isn't a duplicate of another question. I searched on sd_power_system_off and didn't see anything exactly like this.
I'm creating a new project, based on ble_app_template...
I have the 51822 chips, and want to establish a network with large data volume, I use the S130 now, but the effect is not ideal, so I want try the BLE4.2. Do we have the SoftDevice...
Hi,
For the past few weeks I've been trying to make a small device that would simulate a mouse with Arduino and MPU6050 accelerator + gyroscope sensor. I wanted the device...

Hello,
I wish to communicate with the chip via SPI NRF51822.
The NRF chip is configured as a slave. Based on the SPi_slave_example code, I can't set to 1 the semaphore...
I configured my system to sleep after inactivity time.

NRF51822 most time is in sleep mode.
Each 5 seconds it wakes up to make ADC measurements.
But adc_event_handler force only once, but I want to see it every 5 seconds.

I'm new to using the RTT Viewer. It was working fine (all morning). I've only been using the SEGGER_RTT_printf(0, "string %d \n",x); call to dump text and data to the viewer...
Hi,
We are using the BLE keyboard example as a basis for a design and notice strange behavior.
Only change was to create a custom_board.h header for a button press on...
