Hello,
I have an NRF51822 (redbealab ble nano) that I would like to use to count pulses in very low power mode.
Pulses are asynchronous
The rate of pulses can...
Hi
I'm attempting to read a PT-100 sensor value that is part of a voltage divider using a nRF52.
Both the reference resistor and the PT-100 is sampled while the voltage...

Currently using nordic52832 to develop products that use batteries.
We found that the problem is that when the BLE module is connected successfully, it takes 200ms to send...
Hi all!
I am developing an nRF52 application that uses RTC interrupt to measure an ADC value every 100 ms. Depending on the measured value the chip shall either go back...
I am using nRF 52 development board. Using Keil to program it. Its has 4 buttons. We can easily detect when a button is pressed, but is there a way to know for how much time...
I'm using the following code to make the beacon sleep:

Hi
I am sending my BT module with nRF51822 for some regulation test and the Test Lab is using Anritsu MT8852B to communicate with my module through USB-to-UART adaptor and...
Hi team,
I have seen the example of crypto in the SDK_12.3.0. I want to learnt it. But I don't know how to use it, because there is not keil project file, and I hadn't...
I use example from SDK 13 ble_app_uart_c.
I changed uuid to my uuid from nrf51 peripherial device. I get event BLE_GAP_EVT_CONNECTED
where made

Hello,
I have adapted the ble_app_uart_c project for a custom board based on nrf52832. The application already works fine, however, my peripheral is sending four packets...
Hi,
I decided to use nRFUART Example which is inside of the Master Emulator.
I am using nrf51 dongle for connecting peripheral devices.
When I run the nRFUART Example...
Hi,
I am porting my code from SR3 v1.0 to SR3 v1.1 now.
I have a problem in debugging SR3 v1.1.
In SR3 v1.0, it's fine in MDK-ARM debug session. I can set break point...
I have been working on integrating FDS into an SDK13 project using SES v3.24.
I'm not sure if the memory allocations are set correct. If I increase the FDS_VIRTUAL_PAGES...
So I have been integrating FDS into a project under SDK13. It's based on an example that Hung updated for SDK12.1. So after init of fds the method fds_test_find_and_delete...
This crystal, which is used the nRF52 dev boards and reference designs, is now "not recommended for new designs". I could find another crystal that meets the spec, but just...
