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...
My understanding is that the nRF51 is known to need a fairly stiff external pull-down resistor on SWCLK to avoid noise putting the chip into debug mode. I note that the nRF52...
I'd like to know how to implement a bootloader for the Nordic SoC nRF51822-QFAA-R in order to boot the softdevice and some firwmare. If will be great getting an application...
Does nRF52832 have battery monitor?
I can't find in the datasheet if there is an externarl circuit to monitor the battery. I'm using a CR2032 coin cell battery.
Tha...
Hi,
I'm developing some firmware that will hopefully run on a few different kinds of nRF52 device.
Is there a way of detecting if the DC-DC converter's inductor/capacitor...
Following situation:
My device acts as central (connecting to ble sensors) and as peripheral (transmitting and receiving data from mobile). Several services (Heart Rate...
Hello,
I followed this tutorial:

Hi guys,
I am using the RFduino nrf51822 chip. I am using the TIMER2 interrupt and it works fine. But when I try to use the BLE along with the timer interrupt both don...
Hi,
I have have one ble project which is using softdevice s110. so that i want to extend this project by adding DFU service to it like shown here

hi,
i have PCA10028 dk board. i want to flash code in this board using dfu. i have generated Zip file(both soft device and application(example ble_app_hrs example)) using...
I am using this DFU library github.com/.../IOS-DFU-Library . On iOS 10 while processing DFU I receive error RemoteInvalidState in didErrorOccur method with description "Device...
I want to know the maximum range for major and minor in Ibeacon frame, as it is of 2 byte can we set any values from 0 to 65535 or is there any limitation.
Hi everyone!
I'm using the nrf_soc API for get random numbers from the rng and erase and write the flash memory.
In my code, I include the nrf_soc.h file, in the header...
here I have a very strange problem. I m trying to send the data(1 byte) from slave to master,and I have to use the multilink demo because I will have 2 slave devices.
The...
Hello,
I tried to do DFU using MCP 3.10.0.14 and I'm getting the error:
"Error during firmware upload. Timeout while waiting for response for START DFU"
How do I increase...
I have secure dfu working on the pca 10040, and being able to download my own signed app.
However I want to turn NRF_LOG and at link time I get several messages of "._build...
