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...

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...
I am trying to change the radio Tx power in nRF5340. I'm using Zephyr HCI RPMsg for the network core. The datasheet says it should support up to 3dBm. However, the Zephyr...
In the soft device documentation (html) the message sequence diagram for Btle Stack Enable calls sd_ble_cfg_set twice with the same set of parameters. Is this a mistake? The...
Hi All,
I am developing a custom BLE profile for my current project and several of my characteristics are write/notify characteristics. I am finding that when I write...
Hi there,
I just started using Embedded Studio (v5.10d on Windows 10, nRF Connect SDK version 1.4) with nRF52840dongle and nRF5340 PDK. Here is what I did
1. Copied...
Hi, I am developing a new project in which I will use NRF52810. I read in the datasheet that it is possible to configure NRF52810 in LDO and DC / DC regulators mode. My application...
Hello:
Looking at the different demos (applications and samples) available for nRF9160, I noticed that some of them generate multiple hex files while others, only few...
Hi,
I have bootloader programmed in nrf52840. Using OTA I programmed one application region but that application stuck after bootup.
Now how to recover from this situation...
Hi,
I have an existing application built on top of the ble_att_mtu_throughput example. I want to send log data over a BLE connection, and I am trying to use the CLI over...
Hello, guys!
We are using nRF52840 with SDK 17.2. In our system, there is a need to configure nRf52840 as SPI slave device and connect it to some other MCU. Naturally, our...
Hello,
I had a problem with the nordic uart service peripheral. We are using an nRF51822 and the S130 software stack. I had a problem with the app_timer.c STATIC_ASSERT...
Hello guys,
I am facing the following problem:
I created a project from zero, using the Nordic Package for SeggerStudios
--> I selected the option A C/C++ executable...
Hi,
Tried enabling POF on while using S140 with the following code:
The board VDD and VDDH are configured to be 3.3V and in the lab, were dropping the voltage to...
