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 been searching the forums, but were not able to find an answer to my question.
I'm trying to sample 4 analog inputs on the nRF51-DK using the ADC hal. (SDK10...
Hi
I have been trying to get two NRF24L01 chips communicate with each other since a week now, without much success. All what I can find on the net is Arduino examples using...
Hi
I have done several projects with the nRF905. I know the device quite well. Normally I use the CD, AM and DR interrupt pins to determine the status of the device, my current...

The number of GPIO pins connected to this...
Hello,
I downloaded the recent SDK 14.2.0 and installed nRF5x_MDK_8_15_0_IAR_NordicLicense.msi included.
When trying to load the ble_app_template in the dev kit I don...
Hi,
I have a custom PCB board with a nRF52832 and a motion sensor.
I cannot use a signal analyzer on the output from the sensor because of the shape and small size of...

Dears,
I would like to implement a solution for multi-nus(peripherals) to connect one ble_app_multilink_central(centrals). Is it the right way to implement multi-nus connecting...
Hello, I am trying to set my own BLE service, and on the adverstisement initialization I get an error 0x0000000c when calling to ble_advertising_init() .
Why does it mean...
I'm trying to implement a BLE Central device on an STM32 using Serialization to connect with an nRF52-DK board; I've previously gotten a BLE Peripheral working on the same...
Hello All,
I want to write the peripheral code which will send sensor reading to central.
For that I started looking into the Uart_Nus peripheral code from SDK.
I tried...
Hi,
We have a BLE Tx (Transmitter) and BLE Rx (Receiver)
BLE Tx : Nordic nrf51822 (Role: Peripheral, Server)
BLE Rx : Other chip (Role: Central,Client) ...
Hi
We are seeing a significant delay in a flash-related operation on the nrf52840, specifically using the function sd_flash_page_erase() When we use that function to erase...
Hi,
I just changed the ble_app_hrs_freertos example from SDK v 14.0:
APP_ADV_TIMEOUT_IN_SECONDS to 5 seconds in main.c
Enable debug log for various components...
Hi,
We tripped on an odd bug: we were getting corrupted data from flash if Keil's C51 compiler used a MOVX instruction instead of MOVC.
Changing the pointers from generic...
