I am trying to find out the part number of the antenna (I assume it is a PCB antenna) used in the nRF51 DK ( www.nordicsemi.com/.../nRF51-DK) . I found a lot of similar questions...
Hi.
I am using the NRF52 Development board, on Keil uVision, to implement a C program that uses Dynamic Structs. The Structs re-size themselves ( by increasing their capacity...
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...
Hi all,
My configuration:

I'm using an "app_timer" in repeated mode with 10Hz frequency...
I have recently acquired a NAND chip from Micron and would like to use it for storage.
However, looking through the datasheet I found out that the addressing scheme require...
I'm planning using nRF52810 for a new product to reduce the power consumption.
But i worried whether old smartphone with Bluetooth4.0, like Iphone5s can connect with equipment...
I am dealing with the nRF24L01 to develop a remote controller. When I read the specification, I found a specification item, called C/ICO, with a typical value of 12dB in the...
hello,
I'm trying to send long (73B) data on a given characteristic using Android client as the central.
I well received:

Hi to everyone!
I'm following this guide to learn how to use secure DFU on a nRF52832DK board.
All steps have been done successfully, or I think so, until I reach the...
I want to find the agent of China, please, thanks
About Bluetooth and 2.4G, nRF52840/nRF52832/nRF52810
(The agent can provide some technical support and sales)
Can someone please explain the below line mentioned in NRF5 Serial port abstraction layer documentation.
Do not use synchronous API (timeout_ms
parameter > 0) in IRQ...
Hi there,
I want to flash nrf51 firmware from another MCU which is connected to nrf51 with UART interface.
I have seen dual bank serial bootloader examples, in that firmware...
Hi,
I know this has been touched on in other posts but I can't find a definitive answer.
I am making a product that sends data from a handheld joystick to a base station...
Hi All!
we are trying to tune Antenna use DTM over UART from examples.
It is works fine for AAAA IC but doesnot for AABB IC.
Why, what's possible problem?
thx...
Hi everyone,

I need to develop a repetitive task with 10 Hz frequency...
Hi
I am trying to use the serial bootloader to upgrade nrf52 application, but I get verification failure.
I am using nrf52832 with SDK 13.0.0 & S132 SoftDevice v4.0...
Hi,
(1) I look for some methods that suggests is application flag to record. but I set this ble_adv_on_disconnect_disabled = false;. How do I check ble state when disconnect...
Hi
I'm trying to write data to flash and access it via declared const variable.
I can't use UICR because we are on NRF51 and this does not allow to change data in UICR...
