Hi Guys,
I'm looking for some information on how to get data from the secure side to the non-secure side of the firmware. We are building an NB-IoT GPS tracker which is...
Hi,
Is it possible to change the security option of characteristic read or write?
For example , we initial the characteristic as JUST_WORK? Then change it to SEC_OPEN...
I have adapted the " nrf52-mpu-easydma-using-timers-and-drivers " project from Github that I saw referenced in another post and have successfully modified it to work with...
Hi, We are using the heart rate example for developing our firmware, where we plan to send data out every 15 mins. But when we try to increase the advertisement interval beyond...
Hello Nordic Team,
Currently i'm trying to join my custom HID (a joystick) with the ble_app_hrs_rscs_relay example (SDK 16) for a personal project which consist in: a nrf52832...
Dear Nordic,
I am trying to create a simple interface between my PC with Windows and using PyUSB (since it is a simple wrapper, using libUSB as backend) and the nRF52840...

I am looking to understand the state of a pin after calling nrfx_saadc_channel_uninit(channel);
Does it simply return to the last configuration state of the GPIO or something...
Hello, I am using a nRF51822 chip to communicate with a sensor. The sensor continuously outputs its reading via UART every couple of seconds. This is what I am currently doing...
Hi, I'm trying to migrate from the nRF9160 DK to our own board, and I'm having some trouble getting the west build system to play nicely. I've essentially started with the...
Hello everyone.
I have been working on a project that involves DSP and BLE on nRF52832.
The firmware needs to sample an accelerometer signal every 1ms with high accuracy...
Hello,
I am working on nRF9160dk. I have interfaced a GNSS sensor with nRF9160 using UART and receive the data continuously. When there is an interrupt, this data is send...
