Hello,
I'm new to the Nordic SDK and I would like to ask you for help with implementation of PORT events for revision < 3 in "low power" mode instead of "high power" mode...
Hi Nordic,
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:
central app crashes (hardfault...
Hello All,
I am new to this forum, I have been using nRF51822 for a while, and its a great little BLE chip. I am usinga BLE keyboard to send a key to iphone and I captured...
I WANT COMMUNICATION BETWEEN A NRF51422 AND NRF528321 BOARDS, IN WHICH IN NRF51422 BOARD I WILL MEASURE PWM COUNT(IT IS PHERIPHERAL) AND SEND IT TO NRF528321 BOARD WHICH IS...
Hi,
I've been working on a way to detect and prevent replay attacks when beacons are used for sensor data. This is mostly used for home automation sensors, where I have BLE...
Hi,
For our current application we have migrated from SDK 13 to SDK 14. We are using RTOS to handle the functionalities of our application. We replaced our own task for handling...
hello,
I use nrf51822 + S130 + SDK12.2 in my product, nrf51822 work at central + peripheral mode，and i use nrf_duf_flash module for my dfu funtion.
The problem is, i...
Hi,
I am trying nrf52832 with pca10040 board. My app uses s112 soft device and also SPIM0 to collect data from a slave device. No event handler has been used when initializing...
I want to know how to control BLE connection of nRF52832. I am using softdevice S132. I have a device that works centrally and a device that runs peripherals. When the peripheral...

We have managed to program a single serial number into the UICR, using our Development...
I am trying to interface I2C EEPROM (AT24C512) with nrf52840 and I am directly writing to and reading from the registers mentioned in the datasheet. I am seeing the i2c waveforms...
Hello -
We are also bumping into the problem described here , where it is not possible to initialize LESC when BLE is initialized from a FreeRTOS task. The nrf_stack_info_overflowed...

Hi,
I got some troubles on the communication distance between the two units which one acts as central and one acts as peripheral, I tried to adjust the BLE parameters the...
Dear Sir,
I have enabled my project for SPIM+EasyDMA.
I am configuring the SPIM transfer nrf_drv_spi_xfer with additional flags like,
NRF_DRV_SPI_FLAG_NO_XFER_EVT_HANDLER...

At first I set up the RAM size to 0x1F80, it works fine. However, after I try to use RTT to print log, I got the compile error: region RAM overflowed with...
Hi ... how to set the password to secure the connection between the device and application . I don't want to anyone to connect my device , for that i am planning to the set...
I have a nRF52 DK. I'd like to debug my board which has nRF51822 and sensors, and has SWCLK, SWDIO, VCC, GND, RX, TX, VCC, GND. Please provide detail steps on how to wire...
I'm developing a central that discovers services in a peripheral. The services are both custom and standard BLE services. Discovery is working fine, but there is one issue...
Hello,
We are experiencing a rare condition whereby we read in raw Accelerometry data (758 bytes) over the SPI bus, and sometimes (rarely), we'll get a block of repeated...
Hello Everyone, I designed and fabricated a small nRF52 board. The design of this board is based on the Adafruit nRF52 feather. The difference between my designed board and...
