First time here? Check out the Tour!
Hello the Nordic Team,
I come here after a lot of research and testing and do not understand what is going on in my program. (is it Embedded or iPhone nRF Toolbox side ?)
I took the ANCS code ( nRF5_SDK_12.2 ... (more)
I can't get NRF_LOG working with SDK12.3.0. Using the same main.c and sdk_config.h from SDK12.2 - here NRF_LOG is working well - I get no messages in J-Link RTT Viewer with SDK12.3.0. ANY hints ... (more)
I'm developing a project based on the Nordik UART Service and I wouldn't use pairing as in the example.
However I have some problem when a central device is already connected to my nRF52, if I try to ... (more)
After upgrading to iOS 10, I have been unable to successfully interact with my device using the NUS. I used to use the NUS to communication with the device and retrieve stats. For example, I would send a "T" message ... (more)
I was trying to add buttonless DFU service along with NUS service. I used SDK v11. Taken the example ble_app_hrs, s132_with_dfu. And added my existing NUS service. I faced a problem that, both are not working together. If i ... (more)
I have a running board with NUS service (serial profile). This boards starts advertising until a remote device (android nrf UART app) connects to it. then it starts sending some data to the remote device.
My goal now, is ... (more)
I am working on an application which sometimes needs to send a buffer of a couple of KB to a connected smartphone using the nordic uart service.
The function used is ble_nus_string_send() and it can send a maximum amount ... (more)
I am developing a battery powered application using the Nordic UART Service.I intend to use the ble_uart peripheral example as it is , modifying it as per the application.The peripheral is battery powered and has to do both receive ... (more)
I just found what looks like a bug in ble_nus.c in SDK12 - not sure how to report it so I'm just doing it as a question/answer combo.
Previously i've been using the nRF dongle using the BLE NUS Central example to communicate to another nRF DK with the BLE NUS Peripheral example via serial/termite and ble nus.
Could I use the integrated bluetooth device on ... (more)
Hi, I use PCA10040 v1.1 with SDK12.1 via S132 v3.
I use Keil 5.21.
After testing the LBS example, I was merging the NUS (NORDIC UART Service) to the standalone LBS example.
sd_ble_gatts_service_add (which is ... (more)
I am using the BL600 third-party module and SDK 10. I was able to modify and compile project with GCC at examples\ble_peripheral\ble_app_uart\ for s110. It works nice, but the transfer speed is very low (around 500 ... (more)
After I've successfully connected my smartphone via nRF Toolbox's UART-BLE Service to my nRF52 peripheral, I tried to mimic the scenario when the devices get disconnected. This is done by disconnecting the device on the central/smartphone ... (more)
Hi there! I'm using the nRF Toolbox's UART to test the receiving of my data stream. I'm trying to send a data array collected (from spi) in my main loop and send it via UART-BLE to my ... (more)
I am using nRF51-DK with softdevice S130 and SDK 12.0. I am working on the BLE central role with ble_nus_c service. I am able to setup the multiple connection with central and data exchange with them. But i ... (more)
Nordic UART Service (NUS) is a pretty handy way of implementing a serial data transfer service over BLE. The nRF Toolbox on Android makes it very easy to test it, however I could not find any such program (or ... (more)
A beginner's question.
I am using UART over BLE to send data out.
As codes below, ble_nus_string_send() works and continuously sending data out, with the Wireshark's help, I can see notification packet are always sending out.
when I ... (more)
I want to use the NUS service on my BLE communication. I don't have pins connected for UART, do I need to have them? When I try to run the device, my program initializes all the blocks being ... (more)
In my code, I have some 'print'-style functions that write data to a buffer, and that buffer then goes to the Nordic UART implementation. This is user code, and I don't know when it's 'done' printing. Let ... (more)
At a time either ble nus or dfu can work.
I have an problem with the services ble nus for uart and dfu does not work simultaneously means if i am adding both the services in my profile ... (more)
Hello everyone! Frist of all, sorry for my broken English.
I had a timeout handler, which call by application timer every 50ms. In this function I took data from accelerometer via SPI, this method doesn't work. As I know ... (more)
Currently i am using ble app uart as a reference example and nus service with soft device S130 for our project. I want to use multi role example (central and peripheral), in SDK 11.0 example is given for ... (more)
Hello, I find in your source code contradictory values for the UART TX and RX characteristics.
E.g. have a look at nRF toolbox (both Android and IOS) definitions: https://github.com/NordicSemiconducto...
static NSString * const uartTXCharacteristicUUIDString = @"6E400003-B5A3-F393-E0A9-E50E24DCCA9E"; static NSString ...
I seek an advice on the passkey topic. Have been researching the topic all day but still have some confusion. I am running SDK 10.0 ble_app_uart example on nRF51 DK and ble_app_uart_c on the nRF51 dongle. The ... (more)
I maybe running the nRF52 close to its limit. It appears to have a probability of 1/1000 to 1/2000 to hit a 3004 in a continuous time-gated packets stream.
The packets are scheduled in synchrony with ... (more)
I want to make a device which can connect each others and communicate with NUS. I need not to use any other service without NUS. I made nus_c service which is a central side service to use NUS which ... (more)
The nRF UART Android app currently uses a non-monospaced font; so, for example, a '1' is a different width to a 'W'.
This makes it hard to view strings where the fields should "line up".
How can I change this ... (more)
Is it possible to have the data from a Nordic UART Service (NUS) fed to multiple Apps (on the same Android device)?
I am sending IMU data as 20 byte packets through nus service at the rate of 50 such packets per second. The device is a nrf51 DK configured as ble peripheral (S110). The application contains twi to read data from ... (more)
I have a project that uses PStorage and the Nordic UART Service. PStorage is used to store a variable that is updated by the device, irrespective of the Bluetooth, and needs to be sent over the NUS when requested ... (more)
