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 able to establish ... (more)
BLE_NUS_C_EVT_DISCONNECTED of the
ble_nus_c_evt_handler() give a
conn_handle = BLE_CONN_HANDLE_INVALID. So it's not possible to know which peripheral got disconnected when multiple connections are allowed.
I'm using the SDK 14.0 on my nRF52832 with the SoftDevice 132, my IDE is Keil.

Hi, Nordic Forum!
We have developed our own logging module backend so we can store logs in an external flash memory. But now we wanted to transmit those logs via BLE to the phone so we can have a "picture ... (more)
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 ... (more)
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 side (I Guess ... (more)
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.
