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...
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...
Hi Nordic Devzone,
I want to send a packet using send_reliable_message periodically every 3 seconds(using nrf_delay_ms for that) but i get
NRF_ERROR_INVALID_STATE (in...
Hi,
we are working on device that will have Bluetooth in it.
It uses 3rd party Bluetooth module, that is qualified from manufacturer of module.
We are making all CE, FCC...
Hello All,
I am just beginner with Nordic SDK.
I want to send simple hard coded string from Nordic UART service from peripheral to client.
I just tried the below program...
I happened upon this blog post from Estimote where they claim to have increased power output of the NRF52 to +10dbm.

Hi,
I'm using nrf52 dev board on sdk version 14.0 with GCC compiler. I modified the hrs freertos example to add a simple thread with same priority as of logger thread....
Hi
We have problems with Samsung tablets and phones at the moment.
We have an application with two custom services, Secure DFU Service and some standard SIG services...
Hi
I seek your support for the following 2 app_timer (or else) issue:
(1)
in there any reason as to why multiple app_timers will sometime trigger all in a row although...
Hi all, i'm continuing the exploration of the possibilities offered by BLE. I tried the example ble_app_uart on my nRF51 DK, sending for example the number "1" from my phone...
