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...

Hi All,
I tried to use the nRF51422 device UART RXTO events using nrf51 SDK v6.1.
I set the NRF_UART0->INTENSET in app_uart_init() as following:
// Enable UART interrupt...
Hi, I have just managed to successfully read ADC values and send as a service but they are in uint8 format. Is there an easy way to convert this to decimal within my adc handler...
Is there provision for a serialization application processor to control GPIO on a nRF51822 used in serial connectivity mode? Can the nRF51822 be used as an I/O expander?
Hi,
I want to simultaneously read the value from 3 analog pins. For this, do I create just one adc_init function and handler functions or do I need to create multiple initializing...
Connections to my peripheral device are generally very short. I don't really need to have my device request a connection parameters update.
Does this mean that I can safely...
I purchased a pair of FTDI cables, and I can't seem to get them to work.
Unsure if the pinout is standard but here is the mapping of the cables provided:

I am using the N548 with the S310 soft device. I have set up the device for asynchronous communication via the UART. I can send ANT+ commands via the UART and I get valid...
Hi there,
I am quite new to BLE.
I am about to buy a nRF51822 Bluetooth Smart Beacon Kit. But before that I would like to be sure if I am able to advertise battery level...
Hi,
We just recently received our (custom) board with the nrf51822.
To program and debug the nRF I use the pca10028 and the debug out header.
I wrote a very basic program...
I tried loading SoftDevice, Bootloader, and Application using the SoftDevice and Precompiled hex files that come from the example code version v1.1.0. I am using nRFgo Studio...
While attempting to update the firmware from a HEX file, the DFU Application in the nRF Toolkit reports that the upload failed with an unknown error 22. I was sniffing the...
I have a bootloader running on my NRF51822. It uses a relocated vector map in RAM and jumps to function.
I therefore have two debug files and source code sets.
Does...
I am using nRF51 SDK with version 7.2.0, s110_nRF51822 with version 7.1 and gcc_arm and connect the pca10031 board via JLink and try to load bin files but it returns error...
Hi all,
I'm having problems into making the virtual COM port of the nRF51 DK work.
The only line in the User guide regarding it's configuration is the following:
