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...

Hello Nordic experts,
I just received an nRF52840 USB Dongle and I am trying to run one of the examples with softdevice. I am working on nRF5_SDK_15.0.0_a53641a. So, I first...
Hi,
my application runs on a bare-metal nrf52 using softdevice. I need to compress data saved in flash of size ~160KB before sending over BLE and I need to do the compression...
Greetings everyone,
i am trying to migrate from SDK 14.2 to SDK 15 but I got this problem with updating "advertising" and "scan response data". I have read other threads...
Hi, I know NRF52840 support mulitprotocol BLE/Zigbee/Thread. Would NRF52832 support those as well? For cost reason, my smart home application product would really prefer NRF52832...
Hi,
I got one of nRF52 DKs. Is there any chance that we can use this DK similar to nRF51 DK as a sniffer in near future?
I tried to program the board with the HEX file...
Hi all,
I'm interested in the new nRF52840 USB dongle. Currently I'm working on adding some security functionalities to nRF52840 PDK.
Is nRF52840 USB dongle compatible...
Hello,
I am doing a project on a NRF52DK, using SDK15 and SES.
I have been trying to implement a basic feature, which will be a part of a bigger system:
Detect interrupt...
In the course of investigating higher than expected current consumption, I've been looking at nRF52832 errata, and one that I'm concerned about is #78, use of Timer STOP task...
Hello,
I have been trying to merge the pwm_library (or gpiote) with ble_uarte examples to have controle on the pwm signal through UART events
I think i merged correctly...
Hi everyone.
I'm trying to transfer new firmware over UART for just only one node in mesh network.
My node will connect to other wireless MCU(ESP32, ESP8266....) over...
I'm using FreeRTOS and trying to get push button events to fire. The events would fire if I held the button down long enough. I found out that the problem was that "FREERTOS...
Hi
I have a custom board implementation that operates as follows:
Monitoring an input pin waiting for low high transition, BLE advertising of device.
When input event...
I'm having trouble having multiple characteristics for my custom service. My main.c looks like this:
Even though I have 2 characteristics added here, I can see just the...
Hi,
I had a few nrf51822s lying around and as I find the chip and the SDK quite convenient to use, I thought about using them in a small MCU project which does not need...
