I would like to test the newly added v4.2/v5.0 Bluetooth features (e.g. LE Secure Connections, Data Packet Length Extension, 2xSpeed, etc) against non-nordic devices. I have...
I am working on a project using a ble nano (nrf51822) using the Nordic SDK 8.1. In the examples I found a way to control an LED using the methods LEDS_ON and LEDS_OFF. I wanted...
Hello,
I am using ble_app_gls example and I have implemented static passkey in the code. Now I want to see if wireshark shows the passkey when I connect to ble devices. For...
Hi Team,
We are implementing an UART communication between a M4 processor (UART master) and a nRF51 (UART slave) and we want to use the UART in Low Power mode with flow...
Hello everybody,
for my project, i will bond the peripherial with the central.
I test my device with the MCP and can connect without problems. When i press the Bond Button...
Hi all,
I am trying to count the positive edges of a 3.5MHz signal with GPIOTE, PPI and the TIMER1. Unfortunately i can only measure to frequencies up to a little more...

Looking at the CPU...
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 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...
