Using the ble_app_uart example, if I pass more than get a maximum of 60 characters for each call to ble_nus_string_send I get a return code of NRF_SUCCESS, but the nRF UART app only shows the first 60 characters. Is it possible to send more than 60…

I'm working in creating BLE NUS network using 3 NRF51822 FAB, one board has a role as central and 2 other as peripheral. Now I'm able to send string (via BLE NUS) from central to peripheral and vice versa. the problem is i don't know how to determine…

Hi, I add the NUS in the ble_app_hids_mouse example which the sdk version is 14.0. There are four services in the project: dis, bas, hids and nus. When I connceted the 52DK from the nrfUART app, a reset ocurred while I pushing a button to send the…

Hi, We are performing data transfer using NUS service (BLE-UART). Data passed is a 11-character string. READ and NOTIFY permissions are provided for Tx characteristic in NUS service. The string is visible in nrf-Connect Android…

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) BLE Service used : NUS Service On receiver side/BLE Rx, We are…

Hello, I'm trying to make CLI working with UART and BLE (NUS) backend simultaneously. Starting point is CLI example from SDK 14. What should I enable in sdk_config.h and how shuould I intialize CLI with UART and NUS in my app? In ble_app_cli CLI…

Hello Nordic, 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 Bytes/s). When…

Hello Pros, 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 other dependencies at 30ms, 120 bytes…

Hey guys, I'm using the SDK 14.0 on my nRF52832 with the SoftDevice 132, my IDE is Keil. And I merged the ble_app_uart example with the ble_app_cts_c example and the ble_app_proximity example from the SDK. If I start my app, I get the following…

Hi, there NRF51822 SDK9.0.0 and S110 How to subcontract in uart nus mode to ensure that each packet does not exceed 20 bytes and is sent as quickly as possible? The official demo must pass the special character to distinguish the last packet…

Hello, I have had luck in Keil making two NRF52 connect with NUS, central and peripheral. My goal is to have one central speak to multiple peripheral at same time via a piconet. The LED blink example works to talk to multiple BT chips at the same time…

Hi, I was in a process of developing a central device with nrf51422 in PCA10028 board with NUS service client.I use SDK v12.2.0.We have an example code in the library which I modified for multiple devices support.The device connects based on NUS Service…

I'm programming an application that uses the NUS, and I'm trying to test my code using the Android version of nRF Connect. I'm using a nRF52832 on dev board PCA10040, and my code uses SoftDevice S132. I can connect to the dev board and discover/enable…

What's the NRF Toolbox (Android App) UART's Connection INTERVAL? At the SDK12's EXAMPLE's Nordic Uart Service's default connection Interval is MIN_CONN_INTERVAL = 25ms MAX_CONN_INTERVAL = 75ms and this Conn Parameter is conducted by Central…

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_12.2.0_f012efa > ble_app_ancs_c ) as a base…

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 connect a second central, I don't have any refuse…

Hi, 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 completely disable DFU…

Hi, 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 to connect to my board…

Hi, 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 of 20 characters at…

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 & transmit tasks intermittently…

Hi, 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. Basically: Connect to nRF5x normally (treating it as a peripheral) ble_nus_string_send works great…

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. However, the sd_ble_gatts_service_add (which is in ble_nus_init ) returns…

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 to the device and it would respond…

Hi, 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 using…

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 mobile phone. However, on the Toolbox app, I'm not receiving any string…
