Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...
Hello,
Based on aws_fota sample, I want to replace the line with poll with something that not blocks (because I have another things to manage in my loop). Do someone have...
Hi,
I am evaluating nRF52840 DK as a peripheral with 300ms interval with no timeout (continuous advertising with APP_ADV_DURATION set to 0 ).
I understood that while APP_ADV_DURATION...
I am developing for an nRF52810 target application.
I am using IAR 8.42 with a PE Micro debugger. If I debug a project (call it project A), the linker ROM space starts at...
Hi,
I tried the SDK_DIR\examples\dfu\secure_bootloader\pca10040_s132_ble example from nRF5_SDK_16.0.0 with my custom board with nrf52832 mcu.
I followed this guide:

To the kind attention of Nordic support team,
I 'm working on a custom project so that nRF52840 can operate in two different mutual exclusive running modes. A USB operational...
I'm starting a new project that ports an existing (non-Nordic) application to a system based on an nRF52840. My current solution is based on FreeRTOS, so I'm looking at the...
Hello,
We are experiencing 2 different but related app_timer failure conditions.
app_timer_create() returns NRF_ERROR_INVALID_STATE
app_timer_start() does not return...
Hello,
I am using nrf52840 microcontroller and segger embedded studio for making firmware. I made my own project and I am having trouble configuring nrf logging which i...
Hi,
i am working on a Bluetooth application with the nRF52832.
When I try to connect a Pixel 3 (Android 10) via nRF Connect app which is available on store, I am unable...
Hello!
I've got a small problem in Visual Studio Code for Windows, the intellisense can't seem to find the nordic header files from the downloaded sdk. It compiles just...
Greets,
I'm using the aws_iot library atop an nRF9160 successfully to connect and interact with AWS services.
The aws_iot_evt_handler_t callback is triggered when messages...
I'm not sure if what I am trying to do is the proper way to send ble data, and I since I can't get it to work, I'm assuming I'm doing it wrong. What I'm trying to do is send...
Hello, I wanted to send data over peripheral device to the central device by using ble UART example. I used ble_nus_data_send() function in main(void) function. I have checked...
Hi, New user here, I develop using Kicad and it has an antenna based on the Ti SWRA117D design, which is 2.4GHz. Can I confirm I only need two components (as per reference...
Hello,
I am using the SPIM module to communicate the NRF52832 with a sensor, every time it generates an interrupt - which is generated with a frequency of 25Hz. For the...
