Hi, all,
I try to use NRF52832 as central and peripheral. When it is connected with peer as central, I try to send to peer a message with "sd_ble_gattc_write", but I can...
Hello,
I have enabled WDT for nrf52810,S112 with following configuration.
static void System_task_initWatchdog(void) {
NRF_WDT->CONFIG = (WDT_CONFIG_HALT_Pause << WDT_CONFIG_HALT_Pos...
I'm using the nRF52 DK with SDK 15.3.0. At this point I'm trying to get a UART loop back to work by tying the TX pin (P0.8) to the RX pin (P0.9). I have verified that the...
Hi Nordic Team,
In my BLE project I'm creating a Test application which gets all the advertising data from peripheral devices. The complete list of scanned device is received...
Hi,
Good Day!
Problem: We have LED Screen connected to nrf52832 through SPI com and we have some led graphic effects in our application which requires some delay between...
Hello,
I need to send logged sensor data in external flash to a phone via BLE. What is the best way to accomplish this?

Hi,
Q1, Would it send out APS ACK request? so the call back is dealing the APS ACK confirmation, right?
Q2, If we set the call back as NULL, how the buffer got released...
Hi, I used the SPI and SPIS examples to read a type K thermocouple with a max31856, the problem is that in no example do I get any response or data from the sensor, I wanted...
I am trying to understand how to use the non blocking APIs to ensure that the advertisement packet contains the latest data from my sensors. In blocking mode, it is a bit...

I'm implementing communication with an MCU via UART. There are two types of communication – messages, and MCU DFU data. Messages are <256 bytes of data. MCU DFU is >50kb data...
Hi,... =)
I am currently working on a design that has an nRF9160 being powered by a 3.7V Li-Po battery and an accelerometer as well as nRF52810. The I2C bus on the design...
Good day! The technology being evaluated is a thread. As part of the evaluation of duplex data transmission capabilities, there is a need to create the following configuration...
Hello,
I am working on nRF52840 DK with nRF5_SDK_15.2.0_9412b96 and I used the example ble_app_rscs_c with absolutely no changes. I first erased the flash and then burned...
