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,
What is the GPIO pin state during reset, and during startup ? I have seen that it is a high impedance floating input. How much is the value of this impedance? Can I...
Hello,
We're beginning FCC certification next week and I've been creating radio test and DTM versions of firmware that can run on our hardware for the lab. Everything looks...
I am using the nRF51422 for BLE data. My antenna matching network is this:
However, compared to the DK I am getting lower gain (DK gives -50, my PCB gives -64). I have...
Hi,
I want to load both "SPM" and "http_update_ota" code separately to the nRF9160.
For that as suggested in " http://developer.nordicsemi.com/nRF_Connect_SDK/doc/0.4...
I've been trying to configure a second UART for use on the nRF9160 DK. However, I'm having some issues getting anything to send over the UART. I feel like I'm missing something...
Hi,
I use the nrfx_rtc_tick_enable() function to enable tick interrupts for the RTC.
I have a statemachine that in some states disable the interrupt and sometime enables...
Hi everyone !
I want to use serial communication with my ble project. So i tried to implement "/example/peripheral/serial " project into my ble project. I encountered too...
im using Feather EVM. im using the app_ble_uart . after i added SPI to the project i dont get any errors but the code does not run (goes to main) and when i press run it goes...
With an Objective to test mulitple DUTs that provides BLE4.2 data, We are in process of procuring the nRF52840 Dongle.
I would like to understand if i will be able to do...
I successfully installed the NRF9160 DK toolchain on my linux desktop the other day using the "Getting Started Assistant" App, but when attempting to install the same toolchain...
Hi!
I'm currently evaluating Thread using a few nRF52840 DKs.
The network will be used to gather and provide sensor values.
For various reasons, I want to avoid using...
Dear all,
I have two nRF52 Preview DK boards with the SoC nRF52840. I am testing the light switch example on both boards. I have changed the light_switch_server, such that...
I tried some steps and falling back to support. I received my custom nRF52832 board and wanted to kickoff programming the board to meet my requirements. I used nRF52840 DK...
