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...
Our pcb is used for gps location data. We have a nrf24L01 nordic chip as the micro process or between the gps module and wireless module (2G). Our engineer needs to capture...
Hey folks,

Hi,
I'm working on modification of DFU Bootloader to use external flash instead of standard Dual-bank or Single-bank version. Now it works quite well, but I have problems...
For programming the nrf52832's BLE capabilities the only option that can be used is the s132 soft device right?
According to the latest specification, the maximum throughput...
Greetings,
I have an application where the DFU of a NRF52 is performed by another microcontroller via a serial port. Once the DFU is complete, the microcontroller turns...
Hi everyone!
I'm wondering about why SoftDevice stays idle (in terms of radio operation) so "long"
("t ScanReserved" = 760 us) after channel changes during scanning? Despite...
Hi,
I'm trying to do a rough calculation of current consumption for the nRF52840 chip.
The unit should sample 6 times an hour by using I2C to acquire samples from a...
Hello,
I want to program the bare nRF52832 MCU over SWDIO, SWCLK, GND and +3,3V Connections with a Segger J-Link programmer. Unfortunately the programmer could not connect...
Hi,
We are designed our own Beacon PCB based on nRF51822 Beacon Kit...We followed board size,PCB Antenna Trace width and GND Clearance as per Beacon kit...The difference...
As I understand it only the largest physical chip, 7x7mm nrf52840 , supports Bluetooth 5.0 long range. Is this correct?
It seems as if Nordic Semiconductor is abandoning...
Hi,
