First time here? Check out the Tour!
I am using experimental_ble_app_blinky example. In that NRF_LOG over UART was implemented. I Added some UART code for my use. But after flashing code was not working at all. Printf and NRF_LOG_INFO was not working simultaneously. Then i commented ... (more)
I've built a ble app with a custom protocol, but am struggling with storing bonds, when running under freeRtos.
What I see:
hi, I found ble_app_multilink_central example under SDK but this is for LED button application.
Is it possible to configure the same example for NUS?
I worrying about data sharing. As Button and led don't share data and it is ... (more)
I need use nrf51 or nrf52 to do the function . central HID .
have any source ?
Hi, Im using Nrf51422 DK board. When I try the ble_app_multilink_central example in the SDK12, it works on the DK board. But it does not work in NRF51822. (NRF51822 QFAA)
I tried the settings on this link but it ... (more)
I use PCA 10040 as a Central, and PCA 10028 as a peripheral. I want the central to connect and pair and bond with the peripheral.
I use S130 for PCA10028, s132 for PCA10040, both use sdk12.2.0
I ... (more)
i use nrf52832 .i want to connect device and send advertisment data at the same time. But peripheral mode cannot connct device and send advertisment at the same time. central mode caonnot send advertisment data.so how can i use ... (more)
I have set up the peripheral to transmit some dummy data, device information service, battery service and HTS service. I am getting started with the "central" now. Can some one tell me how to use these services in the central ... (more)
I would like to make bluetooth data collector with a serial line. There are max 16 bluetooth devices on the air where I need to collect data. There is a PC which continuosly polling this device by serial ... (more)
I am adding BLE functionality to one of my existing product. I product will play the central role for which I am thinking to use nRF51822 based module.
I learned that central can be developed using softdevice S120. My ... (more)
I have one central(SDK 10.0 S130) and one peripheral(SDK 8.0 S110) device. Normally central device can connect peripheral device it's ok but the peripheral device will stay in metal case. I did some tests and ... (more)
I want to create a whitelist on the Central device. Because there is a lot of peripheral devices around and I just want to connect one peripheral device. First I register the address of the central device to the peripheral ... (more)
Hi, I have a need to connect to a peripheral device from and nRF52 with a Bonded connection.
My device handles bonding when it is a peripheral, but what is needed to enable bonding in Central mode? Is there some ... (more)
Hi, i'm currently using two NRF52 (1 central and 1 peripheral) using the ble_app_blinky and the ble_app_multilink_central.
I would now like to connect my Android phone with the Central in ordrer to control several NRF devices.
How can I ... (more)
I am trying to get a NRF HRS central (ble_app_hrs_c) to make a connection to a NRF HRS peripheral (ble_app_hrs). However, the peripheral does not show up whenever the central scans for HRS device(s). Meanwhile, the HRS peripheral appears ... (more)
Hi, i'm working a BLE gateway with NRF52DK and S132 by using the demo example central uart.
The peripheral equipement advertise manufacturer data like this: 0x0001 during 5sec then 0x0002 during 5 sec and stop advertise.
But I want ... (more)
Can the central device (
ble_app_hrs_c for example) scan for and connect to a custom peripheral device (not nRF based)?
I am using SDK 13.0 and tried to burn in fresh example code (Experimental NFC BLE Central Pairing Reference) to either PCA10040 and PCA10056. However both always shows :ERROR:Fatal in debug terminal. Did I miss out something ... (more)
I adapted the ble_app_multilink example to continuously scanning for ibeacons and collecting rssi data.
Data are then sent via UART to a microcontroller which provides Bluetooth connectivity in order to read data on an iOS device.
I am using ... (more)
I have 2 boards NRF51:
One as beacon (SDK 9), use example code "nRF51_SDK_9.0.0\examples\ble_peripheral\ble_app_beacon".
The other as central (SDK10, softdevice s130), use example code "nRF5_SDK_10.0.0\examples\ble_central\ble_app_uart_c" to read beacons ...
We're using the SDK 12.1
ble_app_uart_c as an example for a nRF52 DK as Central application. Instead of using
ble_app_uart example for peripheral device, we created a new custom service based on
ble_app_template example for our peripheral ... (more)
I download the example of multilink central (S130) into nrf51822 .The central transmit 20 bytes to peripheral interval 50ms sometimes will reset.Anybody know the bluetooth to send and receive the largest interval?
I keep having problems like frequent disconnects (reason 0x08 = BLE_HCI_CONNECTION_TIMEOUT) and NRF_FAULT_ID_SD_ASSERT on my NRF52832 (tested with S132 v3.1.0 and V5.0.0-alpha1) with the central scanner enabled, that vanish when switching the slave latency on the peripherial ... (more)
I want my nrf51422 dk acting as peripheral should able to connect multiple mobile phones near to it. How I can achieve this?
hi, i was looking for example of two nrf52 communication. One is central of course and other one is peripheral. But i have following doubts. 1. If one is central then how peripheral device will connect to central? Are we ... (more)
I need to have a Central device physically connected (via UART) to a sensor. Data is collected from the sensor and sent to a number of Peripheral devices which use the data to perform a task.
So far I have ... (more)
I'm aware of GATT's Profile, Service and Characteristic. And also, for GATT_Server, GATT_Client it can be Central or Peripheral. (As I manually set it.)
And also, the Bluetooth Communication Sequence goes like this.
I'm having a problem at the moment with code based on Espruino on nrf52.
I connect as follows:
ble_gap_scan_params_t m_scan_param; memset(&m_scan_param, 0, sizeof(m_scan_param)); m_scan_param.active = 1; // Active scanning set. m_scan_param.interval = MSEC_TO_UNITS(100, UNIT_0_625_MS); // Scan interval ...
We are using NRF52 and SDK 11 and S132.
The nrf52 acts as a central and selectively connects to the closest phones (ios) that are acting as a pheripheral. For this purpose we have 4 characteristics (TX, RX, RSSI ... (more)
At the moment I am working on a project that uses the nRF52328 acting as both a peripheral and central to connect 3 separate devices intermittently. I am storing their bonding information. A current problem I have now is that ... (more)
