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

Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...
Good evening, I'm looking for a Blue Tooth BLE Low Energy for Low Power application.
This application should consume few mA only when the controller will be in TX and so...
Hi,
Could I get clarification on if the USB peripheral is isolated and won't backfeed?
In my product, VDDH & VDD are powered via a DC adapter that can be unplugged while...
Hello,
I continue to deal with Zigbee and I have another question. I use 2 nRF52840 chips. First nRF as a Zigbee Coordinator (CLI in SDK\examples\zigbee\experimental\cli...
Hi Team,
We are planning for use the NRF52832 Module for our development, In that for Secure data storage exchange we are implemented the some of the crypto mechanisms...
Hello,
When operating the Thingy91 in poor network connectivity environments, the call to getaddrinfo will sometimes block and eventually timeout returning a error code...
Hello,
I am using the nRF52840_DevKit and SDK-v16.0.0. I am planning to build and flash a bootloader with NRF_BL_DEBUG_PORT_DISABLE set to 1, which means APPROTECT and...
Hi,
I'm using SES v4.52b, a nRF52832 module (BL652) and nRF5 SDK 16.0.0. I'm trying to build a generic SPI Read and Write functions with the following:
The device I...
Hi there,
I am in the process of developing a custom PCB using the nRF52833 SoC. This board is quite simple, and doesn't use many of the pins of the nRF52833 SoC.
I am...

Secondly...
hello,
I'm using SDK 16.0 with nrf52832, for storing some information iam using flash storage, during initialization, we are giving a starting and ending address to flash...
Hi friend,
We have a project with BLE connection. It sends out the Manchester data and the data modulates with 125KHz. Can we use PWM to do that? Will the data format be...
My platform is SDK16 with softdevice, MCU nRF52840. I used 2 pin to generate PWM at 125KHz for Manchester coding. I want them are at different pin polarity. For example, if...
Hi all,
I am working with the nRF52 dev kit and the ecg sensor MAX30003. Using MBED to develop firmware.
I am using this library and the example code from maxim ( https...
Hello,
I need to develop an application for nRF51822 that uses SoftDevice 110 v8.0.0 using SDK 12.3 and extend it to use buttonless DFU for the legacy DFU bootloader of...
Hi, support team
I need to realize two-wire uarte receiver(with low power), in the scenario there is no data come from TX in most time, so after receiving the data I need...
