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...
Hi,
I'am tring to test the dfu by secure bootloader.I had done all steps like: Test the BLE Secure DFU Bootloader application by performing the following steps .But I found...
I am implementing an SPI master to communicate with an accelerometer using the SPI HAL directly. My chip is marked nrf51822QFACA11609AC. I have implemented blocking functions...
Hi,
When the UART is configured to use FIFO , i use the UNUSED_VARIABLE(app_uart_get(rxdata));
to read a buffer from FIFO.
how can i also receive a number of bytes...
Hi,
I want to do this cycle with GPIO without interrupting it on NRF51 with BLE softdevice:
PIN1 to HIGH level
read value of PIN2
PIN1 to LOW level
Repeat...
Hello, I'd like to do directed avertising to a central which has a random private resolvable address. My idea: both devices share a pre-defined IRK so the peripheral can compute...
I tried, but it does not work.
for(int y=0;y<100000;y++)
{
if(nrf_uart_event_check(NRF_UART0, NRF_UART_EVENT_TXDRDY))
{
nrf_uart_event_clear(NRF_UART0, NRF_UART_EVENT_TXDRDY...
Hi,
We have a little issue that we at the moment need to cycle power on v3 nRF51822 after DFU.
We have determined the the reason has something to do with the whole complicated...
I attempted to add spi_master as below, but I am in trouble with link error.
If anyone knows the cause, please tell me.

I'm working on a project based on the ble_app_uart_c central example in SDK 12.1. I'm polling the RSSI of a Nordic beacon using sd_ble_gap_rssi_get(), and the fastest update...
I want to handle 3.3v in nrf52832.
NRF_GPIO_PIN_S0S1 -> NRF_GPIO_PIN_H0S1
Can this be this way?
If not, what should I do?
Also, Can the PWM output to 3.3v?
Hi, I use PCA10040 v1.1 and SDK12.1. My desktop environment is Windows 7 64bit.
As far as I know, the J-Link Edu cannot be used for commercial usage.
I so bought...
Hi there,
We've had our own custom controller made, based on nRF52 (Rigado BMD-300 module).
In the last half of January we'll have a baseline firmware working, but we...
Hi, sending a data packet, then sleeping (memory retention mode), then sending another identical packet causes the receiver to send back an ACK for the first and trigger NRF_ISR...
