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...
I want to communicate Central and peripheral devices with KeyPass. Also I want to generate keypass in Peripheral device. But keypass should to include symbols, low/upper case...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...

Hi!
I wonder what is the GPIOs nominal voltage level when I'm using the internal DC/DC converter?
I know that the internal DC/DC converter output voltage is 1,9V but I...
Hello,
we made PCB based on reference with ST balun. In circuit the low freq crystal is optional, so we didnt use it. In software i noticed app_timer use RTC timer. So the...
I am trying to bootload an extremely large hex file using a slightly modified DFU (modified from SDK v5.2.0's example)
The problem is that the hex is so large that eventually...
Im having errors like Arduino is in the while(1) loop if I enable the DC/DC converter in the characteristics and generate service.h file , If I do not use this setting everything...
I have a NRF24L01 board, which acts as a receiver. It listens on RF channel 2 using address pipe 0 address as follows 0xC47B4D0331. I am able to transmit to this NRF24L01...
I need to wake my uC from sleep when the nrf8001 gets in connected mode and for that I need to supply an external interrupt on hardware interrupts on the MCU.
Will active...

I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi
In my project, we wanna transmit large amount of data from UART master to nRF5182, and then to iOS7. Baud rate is 19200. Feed-in speed is near 2KB/sec. BTLE transmission...
I am trying to use this android app to read/write values from my nRF8002. Every few seconds I get a request to bind to the board, even if I already accepeted to bind to it...
I have a example using nRF24LE1.
So. I want know what can I change that example. or how to I get nRF24LU1+ example.
nRF24LE1 example is this.
