before i write the flash, it has been erased.so ,its value is all 0xff.
when i write 0x00 to flash address 0x0001,the value read out is not 0x00 but 0x01,and the value in...
I'm looking for a way to use the nordic uart service ( devzone.nordicsemi.com/.../ble_sdk_app_nus_eval.html) from Linux using the native Linux BLE Stack (BlueZ). My application...
Hi,
I've created an application using the S110 experimental ANCS demo. I successfully implemented ANCS and then began to structure my application around it. At some point...
Hello,
In an ongoing company project we use a couple of nRF51 transceivers forming a beacon enabled wireless sensor network consisting of one base station and multiple...
I want to count clocks in order to implement a watch. I use the RTC0 as my time-base and count mainly with this device. As it has just 24 bits it would not last for long,...
Hi,
how long does it take time if i would wake up a nrf51422 rev2 (ANT and BLE) in deepest possible sleep mode ?
And how long does it tai if after wakeup it had to communicate...
I saw that the app_timer uses the SWI0. Could you explain what it does and what the advantage is compared to "timer_list_handler_sched()" calling "timer_list_handler()" directly...
Hi, I'm working on an extremely space-tight design and need some clarifications. It is an nRF52832 QFAA chip with a Johanson 2450AT18B100 chip antenna.
Up to this point...
Hi,
I would like to use higher dBi antenna instead of the DK pcb antenna. Can I say the pi-network before J1 (measurement point) probe is 50ohm? Hence I can just remove...
I am trying to control another BLE device with nRF52xx. For controlling the device I need a terminal for connecting, disconnecting and switching on & off a sensor. I have...
I am using NRF52DK and trying to debug an SPI transfer, using SEGGER_RTT.h to print. However, printing of the logs are not consistent. Some debug lines do no appear in the...
Hello,
The only semi-official information that I can find regarding the differences between PCA10040 1.1.0 and 1.1.1 DK boards is this post . It suggests that there are...
I recently ordered two NRF52840-PDK and a Segger J-Link Base to program/debug the boards.
Then I just read that the development kit have a J-Link OB included, or I could...
Hi.
I wonder that how to setting continuous modulated output mode for nRF24L01P.
I see Appendix C - Constant carrier wave output for testing in datasheet.
But there is...
I see in the SDK 13.0.0 release notes that the NFC type 4 library was updated to "production ready", but I couldn't find a summary of the changes made to the NFC Type 4 library...
So... As I understand it, micro-ECC is a free library that lets you create an ECC private key for signing the SecureDFU that Nordic is using.
The nrf52840 has Cryptocell...
I've put on the stock dfu/bootloader_secure on the nrf52 DK.
I've then create a distribution ZIP and upload a blinky app to the DK. That worked fine.
Then I compiled...
Hi,
I have problem with DFU for 51822xxAB witch has 128kB flash.
I use dual bank bootloader for nrf51422xxAC witch has 256kB flash memory within nrf51822xxAB.
Ofcourse...
I know this might be a dumb question to you all, I am first time doing this sort of work
How to connect Jlink to NRF52? I need to flash a custom built BLE board with new...
I'm running on a nrf51822 chip, using Keil and a JLink Segger programmer. I'm running on SDK 12.2.0 and I believe I was correct in choosing pca 10028 s130 but I'm not 100...
