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...
Hello all, at present time I'm making investigation of BLE link stablility at harsh megapolis environment and at long open space ranges. During testing I found out some information...
Looks like there is an error in the nrf_drv_gpiote_common.h :
#define INTERRUPT_PRIORITY_VALIDATION(pri) STATIC_ASSERT(((pri > 2) && (pri < 4)) || ((pri > 5) && (pri <...
Hi guys,
So as I'm migrating from SDK10 to SDK12 I've noted that the app_pwm module is consuming more power then expected while disabled ~300uA. After initialization, I...
Platform: nRF52-DK using SDK12.1.0 and S132
Summary: Using nrf_log module from SDK along with RTT by setting NRF_LOG_BACKEND_SERIAL_USES_RTT flag causes nrf_log_serial...
For example, in SDK11, the file:
components/softdevice/s130/toolchain/armgcc/armgcc_s130_nrf51822_xxaa.ld
Contains:

Not a question, but a big thank you to Nordic Tech Support (Kristin) who reviewed our nRF24 design several times until we got it right :)
Implementing the recommendations...
Hi,
I am creating the first prototype for my BLE product and for now I used the suggested layout from the datasheet, but I am kind suspicious of that layout it seems very...
I follow the example, as below
nRF5_SDK_12.1.0_0d23e2a\examples\peripheral\flashwrite
but I only get some error, can not get anything, and the ble is unconnected.
Hi there. I'm making a sensor system which is intended to measure an ADC value, and send it using the Heart Rate Sensor template. To make this, I've rebuilt the ble_app_hrs...
Hi
Does the newly released nRF52840 chip have pins on the side, corresponding to the "outer ring" (A8-23, AD2-23, B1-W1, ...) pins on the underside of the chip, like this...
hello i am interfacing i2c sensor mma8452 with nrf51 dk. my function is
