Hi All,
Please Reviwe for a attached circuit file(Chip ANT of nRF51822.pdf).
I also attach a datasheet of chip antenna applied for that circuit(SDBTPTR3015 Data Sheet...
to me it made sense that EN_AA settings are controlling the receiving pipes if an ACK has to be sent back upon receiving a valid packet.
then i thought that the settings...
I am using BLE_Gateway example defined in nRF51-ble-bcast-mesh to create an rbc_mesh over 2 nRF51422 devices . For now, I am just testing it out on 2 nRF51422; I will set...
Hello,
I see when you import an example from the pack installer ( for example pwm, ble, timer examples ) it arrives with the misc controls --c99 on by default , so I cannot...
Hi,
We're looking for a low-latency 2.4GHz solution (not BLE) and the nRF51822 is oft-quoted as providing low latency, but what are the typical ms figures we could achieve...
Hello all,
in my previous question (Switch between applications (multiple services.h)) I got the advice to merge my two services into one service, including a HID over...

I was just looking through the code in the HIDS module in more detail, now that I have built a few demo HIDS apps I want to make sure that I understand the HIDS module...
Hi,
Is there any other define to change than SERVER_COUNT in main.c of client's light control in order to run the example with only 1 client and 2 servers (instead of 3 servers...
I cannot get the output from the is the example the UART buffer gets filled but there is no output to the tty.
The interrupts seem to be set, but I don't see the interrupt...
Hi
I am using nrf52840 for indoor positioning application based on RSSI. I was wondering if somebody has a tip how to calibrate the nodes before doing the experiment.
Hi,
I'm using sdk12.3.0 ble_app_uart.
My problem is BLE connection.
Sometimes(almost 50%)I tried to connect BLE but fail and I have to connect again.
I don't know...
Hi, I'm contemplating ways to drive a small RGB LED matrix with the nrf52832 in a really space-tight project. Ideally without any external components. I'ts maybe around 40...
Hello,
I need do synchronize the time between two NRF52 devices. One is connected to the other by a custom BLE service. Do you have any ideas how this could be done?

I'm trying to integrate buttonless DFU with secure bootloader with bonds with the DFU.
Using SDK 14 with SD 132 v5.0.0.
Using projects: secure_dfu_ble, ble_app_hrs_freertos...
Hello:
When I try to open an example project from nordik, keil doesn't open some files and I get the following error:

SDK v12, SD130 on 51822.
I init uart through APP_UART_FIFO_INIT, and installed uart_event_handler. UART rx/tx with an external MCU works OK while softdevice running.

Hi. I have some nRF51 firmware I'm migrating to the nRF52. It's a peripheral with bunch of vendor specific services, using SDK 13.0.0 and SD 132 v4.0.2.
My code builds...
Dear Nordic,
I am trying to send the sensor data via beacon. I am regularly updating the manufacture data (through which I am sending the sensor data). But while executing...
In fact,there is a demo on internet, and I test it ,but I found that the event is not reliable! my code is :
