Hello,
Could someone give me a hint with the following problem?
I am using two example projects (ble_app_uart_c, ble_app_hrs) to connect a central and a peripheral.
An...

the generated xml file...
I read this older post ( devzone.nordicsemi.com/.../) and have a similar issue but with enough differences that I felt it was worth a new question.
I have an STM32 MCU...
I am having an issue with running the initial blinky example that came with the nRF51 PCA10028 SDK in the Eclipse IDE . I will include screenshots of the issue. I believe...
I use nRF51-DK and nRF51-Dongle for a BLE sniffer.
Always the sniffer fails and marked with an error "Encrypted packet decrypted incorrectly (bad MIC)".
It can not be...
Hi,
I'm using long write in one characteristic but if I try to configure this characteritic with write authorization (attr_md.wr_auth = 1) it doesn't work. I need to send...
What does the QSPI controller inside the nRF52840 do when the ACTIVATE task is started?
Does the ACTIVATE task result in communications with the external QSPI part such...
Hi,
I have a question about the UARTE peripheral.
is it possible to keep the DMA running and let it write to ram in a circular way?
I used DMA on the stm32 before and...
Hi there,
I'm a beginner with NFC and there is somethings I don't understand with the NDEF Messages frames. I have a the PCA10040 Development Kit.
I've seen this schematic...
Hi All!
I would like to implement the DTM nterface over USB VCOM instead of 2xUART (from examples).
Is it possible co-work USB driver (VCOM) and DTM from samples together...
Hi All,
I use 2 peripheral and 6 Central roles coexisting.
Not clear the order of conn_handle number assigned by SD during BLE Connection.
For example.
After Central...
I am new to nRF programming. My "far away goal" is to make a BLE sensor mesh with a centralised data collection.
Currently I am deciding what libraries to start playing...
Peripheral device has 2 services,but central can find only 1 service(0x1001).
I want to find other service(0x0001)
According to the message seems to be looking for 0x1001...
Hi,
I'm using the nRF51 dongle with nRF SDK 12.3.0 and the S130 2.0.1 SoftDevice to implement a BLE central. The dongle repeatedly connects to a BLE peripheral, performs...
I'm running the PB Remote Client on a PCA10040.
I have 2 servers running on PCA10040 boards.
Watching the log whilst debugging the client, I receive the following: ...
Hello all,
I am new to nRF platfrom, I am working on a protect which contains multiple BMD-200 modules with nRF51822 controller. It has to transfer some data via UART,...
Per this blog, I understand that the nRF52's ANT pin must be matched to 50ohm via L1/C3 and that the antenna must be matched to 50ohm. Hence a trace with 50ohm characteristic...
Hello, the title is pretty descriptive.
I've tried to read through previous questions and got a rough idea but decided that it would cost too much time for me to explore...
