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...
Loaded Softdevice S140, ( Using NRF52840 DK board ) using NRFgo Studio.
App flash base is set to 0x00021000 and app RAM base is set to 0x20003000
Looking at the CPU...
In our earlier projects with nRF51 and SDK 8 we used to have bluetooth device names of length 13 or 14 characters. However, when using nRF52 and SDK 12 I noticed that the...
Hi,
What is the best way to read the state of an output pin? I have an LED connected to a pin and want to know in a different part of the program whether the LED is currently...
I am having an app_timer (nRF52832 / SDK12.0.0) that's interval must be changed during its lifetime. I am using following code to change the interval:

Hi,
I'm trying to use the command "mlme_start_req" to setup the device as a pan coordinator to send beacons to the others devices in the network, but after submit the command...
Hello,
In my application, a peripheral will be connected to many central devices, and the application includes buttonless dfu service.
It needs pairing (encrypted connection...
Hi,
I have a device with nRF52832 and firmware is composed of Bootloader (BL), softdevice (SD) S132 v2.0.0, application and I am using SDK 11.0.
I have created different...
Currently, we are trying to have the nRF51 chip working with a type of capacitive pressure sensor. We did quite a lot of work on searching proper circuits of reading the capacitance...
I have 2 board nrf52840 DK, I now I want to send file ( 1~2 Mbyte) from board_1 to board_2 without use UART. where can I get example to do that ?
PS: I also need example...
I've merged the experimental_ble_queued writes sample code into my project and am testing the long write characteristic with nrfConnect from an Android phone. I get no errors...
Hi,
I am trying to figure out the reboot reason on an NRF52 in order to solve it in the best way.
We have a design with a dual supply 3.6V/5V going through a 3V LDO...
Hello,
i have a BLE Peripheral that has a service that we use to simulate UART over BLE. Very similar to the nRF UART. I consider the time to establish a link that allows...
Hi all,
I am trying to save an UART variable I am receiving. My case is very similar to the example Flash Write Example, but I would write few bytes instead of the whole...
Hello!
I have to sample audio signal from a microphone (MAX 9814 adafruit) with the nrf52 board. I use the saadc and then I perform a FFT of the data using the sdk 13 examples...
I implemented my profile based on GLS example. my profile has five services and every services have several characteristics. Pairing with several smartphone work properly...
