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...

Hi
I have tried to make use of the FDS for storing data and encountered this behaviour.
The required setup of the sys_evt_dispatch() & fs_sys_event_handler(sys_evt) are...
Hi,
were are looking forward to redesign our PCB. The nRF51822 will communicate via I2C which sinks up to 3 mA and 15 IOs will source the maximum rate of 15mA. Additional...
Hello,
I implemented a function to add characteristics to a service, but I'm having a problem when I add notifiable characteristics. I pass a set of flags to my function...
Hi,
I set a debug LED on as the very first thing I do in main. Randomly (sometimes 2 in a row, sometimes 1 in 100), sometimes my debug LED never comes on and no code is executed...
Hey Everyone,
I am new to nordic development. I am really used to programming with easy environments like the Arduino. I have seen some examples using the printf() command...
Use the Nordic \ nRF5_SDK_12 _f012efa 2.0-3 d \ examples \ peripheral \ pwm_library routines, now can output two lines of PWM, but want to two way different PWM phase have...
Hi there. I'm Matthew!
I noticed that there were contests sponsored by Nordic in the past, such as
Startup Weekend, June 15-17, 2012
The Nordic Semiconductor App...
I can use nRF Toolbox as a central to test various nRF5 as BLE peripheral samples.
Is there any sample app (iOS or Android) to test the few nRF5 as BLE central samples? ...
Hello.
I am trying to turn off ACK in the example "esb_ptx". I have tried this in both SDK 12.2 and 14.0.
I try to turn off ACK like this:
