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 doing a more complex application than what I'm showing here, but I've reduced it to the minimum. I'm initializing the RTC subsystem, creating a timer, and starting that...
Hi all:
I use the softdevice 2.0.0 and compile bootloader example with "dual bank" on the nrf52 DK,
Running a system that can using DFU from app then jump to bootloader...
Hi ,
I search and found some of questions on this forum wich speak about enabling and disabling peripheral.
I'm ok with that but i have a question about there initialisation...
I am testing the Nordic nrf51822 chip.

Hi,
I'd like to transfer some data from my App (using fstorage) to the bootloader (using pstorage).
Given that that the two storage mechanisms are different, how can...
Hello, I've been working on porting a bit-banged control of a peripheral to use nRF51 SPI--which is just SPI rather than SPIM (therefore no DMA). Observe the SPICLK waveform...
Hi guys,
I am developing a project where I have a large group of NRF52 chips together in one room. In their normal state each chip is paired as a BLE peripheral device...
We are working on a NRF52 DK. In the data sheet of NRF52832, there is no mention of enhanced shock burst mode or dynamic payload or multiceiver. Do I need to refer additional...
we're using Mbed for NRF51822. our board using 2 GPIOs interrupt.
problem: the Rise edge did not generate the Interrupt event: set EVENTS_PORT.
I try uisng while, but...
Hello,
I will explain my setup:
I have 2 nRF51-DK each one of them connected via I2C and SPI to two different custom boards. One being the central(nrfA) and the other...
