First time here? Check out the Tour!
I'm trying to implement a BLE Central device on an STM32 using Serialization to connect with an nRF52-DK board; I've previously gotten a BLE Peripheral working on the same setup (in this case I'm not trying to ... (more)
HI, I found that the maximum number of connections 52832 can only be 15 connections, like this
// <o> NRF_SDH_BLE_CENTRAL_LINK_COUNT - Maximum number of central links. #ifndef NRF_SDH_BLE_CENTRAL_LINK_COUNT #define NRF_SDH_BLE_CENTRAL_LINK_COUNT 15 #endif
When I set up more than 15 when the compiler ... (more)
Hello, I am using ble_app_uart_c and ble_app_uart example for data transmission between central and peripheral. I am able to transmit data successfully. I would like to know the time difference between transmission and reception. Are there any methods to find this?
I'd like to buy a large amount of Nordic modules with Central and peripheral function with UART interface (similar to HM10 which is based on TI). The purpose is to build a MESH network. Are there manufacturers that can ... (more)
Hello , I am using nrf52 Dk and nrf52832 custom board for testing ble communication. I am using ble_app_uart and ble_app_uart_c examples to test ble communication. In my custom board , I connected P0.6 to Rx of CP2102 and P0.8 ... (more)
Hi, I am trying to add a notification charactersitics on client, I am able to add one of them, but when i try to add another one sd_ble_gattc_write(), result is always NRF_ERROR_BUSY. I am calling this cccd_configure() with same conn_handle ... (more)
Anyone know how to put the nrf51822 firmware again? I made an update and deleted it from the kit. Where can I find it?
I would like to know if it's possible to pair two NRF52832 together using NFC. NOT an android phone to an NRF52, but a central NRF52 standalone connect to a peripheral NRF52 standalone. Can the NRF52 generate RFID tag ... (more)
Hi, I am using NRF51822 and sdk12.2. I am using Softdevice s130 with peripheral experiment_ble_blinky example. I have merge UART example in this and it is working fine.
Yesterday i flashed and it was working perfectly. Even i connected ... (more)
Hi, I am using NRF51822 and GCC compiler. I am using softdevice S130. SDK 12.2. I want to receive the data from Peripheral that is one way only. I want to use multilink central application on NRF51822. When i ... (more)
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 ...
