I'm analyzing app_timer scheduling code..
I have an question about list_insertation_handler function in SWI0_ISR
I think if ( (p_timer->ticks_at_start - m_ticks_latest...
I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...
A time T_PINR is specified in the datasheet, as shown in the snippet below.
Does this give me an indication of the pulse width for a pin reset? If so, how do I interpret...
Not really a question, just that I find the comment misleading. In the sdk_config.h example coming with the SDK there is this piece of code:
// <q> SAADC_CONFIG_LP_MODE...
Hello,
I am trying to establish communication between Win 10 PC and nRF52 Dev Kit using pc-ble-driver . I followed the instructions in:

RN2903 is LoraWAN module using ASCII Command Interface over UART.
RN2903 is connected with nRF52-DK.
I'm connected uart line tx, rx gnd.(cross connect...)

Hi,
My desire is to connect a BC832 module (with nRF52832 on it) to a UART on a controller board and then send data from an iOS app (programmed in Swift) through the BLE...
Hello,
I need two signals with a phase shift to control my motor. For some reason, completely randomly, sometimes my GPIOTE event is not triggered and i get the inversion...
Hi All,
Based on nRF52832 SDK14.2 rtc example, I want to change it to retrigger RTC Compare0, let the LED1 also toggle every 3s, instead of keeping LED1 on. I tried to add...
Hi, guys, I have an IR receiver module with 3 pin (AX-1838HS) ?
How can I use it on my nrf52832 ? I have PCA10040 development board. I don't know how to connect them and...
I need to drive a stepper motor without software intervention, since strict timing is a must.In the following image you can see the required wave-forms - the motor requires...
The SD API (S132-6.0.0) documentation provides little beyond what one could guess from the function and type names. sd_mutex_acquire says "Attempt to acquire a mutex". nrf_mutex_t...
Hi i am doing a prosject to get notification on cell phone when i get mail in my postbox (postbox outside the house) I am using a nRF51 dongle, and want it to connect to cellphone...
Hi! I'm working on HID mouse example on SDK 13.0.0. I'm supposed to use this as a low power media button control. I've done a few modicifations on the code for power optimizations...
I know that few companies choose to use NRF528001 with a separate microcontroller like Fitbit.
I would like to know why would they do so instead of using an NRF52 chip that...
