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,
I'm trying to modify the SPI Master loop back example into a 4 line SPI Master_Slave program. Whenever I change the Tx_Buffer_lenght from 10 to lsome other numbers...
Hi,
Here is the piece of code that is bugging me.
The code algo is at every 500ms timer2 interrupts, and the adc captures 1500 samples and stores it in an array .I always...
I'm using nRF 51822 to develop a proprietary wireless protocol.
At Rx side, every 500ms have a listening window with 10ms to listen if there is package to receive. So 10ms...
I am testing with SDK6.1 S110 7.1. I've noticed that when I try and update the Bootloader image using the Android MCP app, everything updates fine. I have logic in place that...

Hello all,
I have an ANT project which is running fine using S210 SoftDevice (SDK v8.1.0).
Now, I am trying to extend this project for BLE operation, by switching the...
I have my devices programmed in a way, that they decide whether to enable SD and transmit via BLE or to keep it disabled and start operating using Gazell.
In this case I...
So Segger recently asked me to update my Driver to V500j to be able to run my new J-Link programmers. However this update has completely bricked my Test Software which uses...
Hello,
I would like to ask you if anyone wrote Python script for connecting PCA100000 dongle to computer and using it without Master Control Panel. How this can be done...
I know this question was raised here a couple of years ago but it seems to me the API was changed since that time. If I set the timeout to 0 and use BLE_GAP_ADV_FLAG_LE_GENERAL_DISC_MODE...
As I understand the SPI HW driver documentation, it appears to be at least biased for using a single chip select (slave select in the API). I have an application where I have...
Seeing recent response to my original question on multiple chip selects, I've opted to share a modification to spi_master that I've implemented in part to make handling some...
I have the follow code in my application for a PCA10028 program from the nRF51 Development Kit (S110 v9.0):
