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...

An...
Hi,
I'm using nrf52 with S132. I noticed high current draw after calling sd_ecb_block_encrypt() function.
After calling function consumption is 6mA and stays at a constant...
Hi,
I would like to read and update value of the characteristic received from AD pin AIN0. I already tested the following code, where I got very weird results (value is...

1 – As anyone already...
HI,
I have very basic question: I plan to connect two devices on i2c to the nrf52. Can they both be connected to the same pins, and configured by software to select one...
I have been analyzing the Bluetooth snoop file on several Android devices, where the Android device is the Central (Client) and the peer device (nRF51822 with S130) is the...
Hi,
I am new to MCUs and I am trying to send information from NRF51 via UART (not BLE UART) to Putty. No matter what I try I can't seem to print anything on Putty. I started...

Hi there,
In the process of moving from SDK 10 to SDK 11, I've also been migrating an accelerometer driver over from using straight nrf_drv_twi code to the higher level...
Hello,
Is it possible to use easyDMA to transfer from GPIO to memory without involving the CPU? We need to read from a parallel bus for a short duration, without losing...
When setting up a 1Mhz square wave using NRF_PWM on the NRF52 or GPIOTE on the NRF51 while BLE is advertising, the PWM stops when the radio is active. The problem doesn't...
Hi,
I'm developing a BLE application for the nRF52 and I wish to use directed advertising and the whitelist.
I initialise the Bluetooth advertising using the following...
