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...

I'm writing a central app using the pc-ble-driver project with an nRF51 dongle. This is to test our product, which is a peripheral using the nRF51822. The test central needs...
Dear All,
I have developed a BLE system in which nRF52832 is being used as a peripheral and central concurrently. I am also using BLE_GAP_CONN_SEC_MODE_SET_ENC_WITH_MITM...
Hello,
I have board pca10040 V 0.9.0 2015.41. When I program nrf and then issue a nrfjprog --reset -f NRF52 everything works fine, however when I execute nrfjprog --pinreset...
I don't understand OOB used in BLE security part.
Is this a communication out of 2.4 ~ 2.48 GHz frequency band?
Or is this one of method of pairing procedure(to generate...
Im currently working on a project and long story short im stuck on getting the nRF24l01 to communicate. I believe I have the Tx side of things working, however as I do not...
Hello,
We have connected Nordic+ MPU 9250 and able to read sensor values through UART display, but we wanted to do some excercises and read values, but it's not possible...
Nice to meet you.
The chip uses nRF 52832.

Hello Nordic team,
I'm doing a migration of my nRF51822 (32 RAM / 256 Flash) application from SDK10 (s130_1.0.0) to SDK12.2.0 using the s130_2.0.1. So I took the experimental_ble_app_buttonless_dfu...
The way the example projects, including the app_template are structured, they will only build if inside the SDK folder.
The main problem I find is that the Board Support...
I want to use ANT and BLE concurrently.
I found that there are no multiprotocol examples in SDK12 for NRF51422 (PCA10028). It only have example for NRF52832 (ble_ant_app_hrm...
Hi all,
i use softdevice and app timer.
I know that the softdevice use a RTC0 and app timer RTC1.
I would use a rtc to have a timestamp. but i see that after 512 second...
My function need a time window to get value from sensor,but the prcess always interrupted by SD.I know that the priority of SD is higher than app functions. So how can get...
Hello friends. How to write a number to and read from internal flash. My information about the microcontroller is very weak. I use STM32F103RET6 .
