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...

Hi,
I'm trying to compile a simple example (light_switch__server_nrf52832_xxAA_s132_6.1.0) for Bluetooth mesh with Segger embedded studio. I'm having a hard time to get...
In nRF5_SDK_15.0.0_a53641a code, there's such definition:
#define UART_DEFAULT_CONFIG_BAUDRATE 30801920
Which means about 30.8 Mbps.
But in page 345 of nRF52832's...
Hello,
I'm using a nrf51822 board as a DFU controller to update another board's application, the client board runs the bootloader secure example. When I write data to the...
This is almost certainly a noob (to nRF52840) programming question.
I have modified the peripheral/gpiote example to invoke an ISR on the falling edge of a pin signal. In...
I am trying to use the Sparkfun nRF52832 breakout board as a master in I2C communication. I am using Arduino IDE to program the module. I defined pins 24 and 25 as SCL and...
Nordic Support, Let me first explain what I would like to achieve. I am developing a line of devices that will act as GATT peripherals. I would like average current consumption...
I have a custom board with an nRF52832 (CIAA-B0), and I am trying to use the SPI Master.
When I use SPIM1 or SPIM2, the transaction hangs, but the same code talking to SPIM0...

We are looking for Sub 1 GHz RF Module, which gives Longer Range distance in Field either in LOS or NLOS.
Please share the details regarding proven...
Hi guys,
We've written a small test on-top of our internal Bluetooth library (glorified wrapper sat on-top of SDK 15.2.0 SD140 6.1.1) on the nRF52840 to send dummy bulk...
Good morning everyone,
I am implementing a custom radio protocol on NRF52 without using the SoftDevice at the moment. For some reason, I get a HardFault which I am trying...
Hello everybody,
I can flash my custom nRF52832-based PCB using the nRF52 DK and Segger Embedded Studio or nrfjprog, but this requires that I always have my computer with...
Hi,
I need to get 1.8V on the VDD using high power mode. According to the documentation this is the default value. However, I measure 3V.
Please advise,
