Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,
I've built a small BLE-device based on the nrf8001.
With my Iphone I can discover this device and I am able to connect to it and listen to notifications of the...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi!
I have trouble in flashing a simple nrf51822 via the nrf51-dk.
Can anyone ensure me that this simple wiring should be able to upload an hex file onto the nrf51822...
The Peer Manager is currently in experimental state and is not recommended for production and same for the device manager for some sdk.So which SDK should be preferred
Hi,
Im using S130softdevice.i wanna make dimmer by using experimental_ble_app_blinky project on gpioet
But i have a problem with detecting 10 milisecond time (it means...
Hi,
I am new starter in Nordic platform. I am using device nRF51822-CFAC, the SoftDevice is S130_nRF51_2.0.1(Id: 0x0087).
What I am doing is to put NRF51 into system...
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.
