Hi,
I am trying to run nRF24L01+ in default configuration using simple ping-pong examples using RF24 Arduino library.
The problem is that while ping-pong is getting through...
Hi,
I want to send data from one peripheral(nRF51 DK) to multiple Android Phones. This will be a one way connection from the peripheral to the smartphones. I red on the...
I am working on "nRF51_SDK_8.1.0_b6ed55fnnn\examples\ble_central_and_peripheral\experimental

In this project,in which variable...
Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello, the official example of BLE peripheral communicate with android device using GATT HVX NOTIFICATION. I'm wondering, if I need to send data over 20 bytes, are there other...
Hello, I wanted to show here two cases that made me crazy today and I fixed using workarounds, but still have no idea why they are happening.
In main context I call a function...
I m using two Arduino pro mini(3.3v,8MHz),nrf24l01+ modules, when i first used those modules they worked fine they were communicating well(used the program from here arduino...
Req: I am using nrf52 EVK kit for our project and project involves capsense , vibrational motor / sensor and accelerometer (to be used in future).
Question: so what profile...
Hello,
I use nrf51822 as peripheral and after connection with central module(nrf51422 dongle) I want to set a period(10 s or more than 10 s) in which Softdevice will have...
Hi,
I have already read several posts and articles about how to maximize data throughput on Bluetooth Smart (like sending multiple Notify packets with 20 bytes of data...
Hello,
How can I port the code written for nRF51 to nRF52 in Keil IDE.
Also, I see that Keil supports nrf52 but does not provide device specific software packs.
Is...
I want to use the automated test function of the master control panel.
I want to test the device information service and wrote this xml script to connect to the target...
Hi there,
How could I receive a large data from phone, example 120 bytes from a characteristic. So far I was able to receive 20 bytes.
From the working code of 20 bytes...
Hi
Try to send characteristic notification by invoking sd_ble_gatts_hvx() with the following parameters:
uint32_t err_code = NRF_SUCCESS;
ble_gatts_hvx_params_t params;...
I do run the “nrfjprog --pinreset”,later, the nrfjprog can not find the nrf51 device,WHY?
the nrfprog version is V5.2.0,
I use nrf51822qfaa,s110,keil,etc.
Hi, Guys,
I have a question about chip operation temperature. Will the chip auto reset when the temperature over 75 C? I checked the nRF51822 product specification v3.1...
I would like to learn more about when it is safe to invoke soft device methods and when it is not. For example, are the following 'allowed' to make soft device calls to update...
Update to below: I get data out of the VCP and into Termite for a sub-second when I first power the board (with handshaking enabled), then I get no subsequent data (even though...
