Or is there any LCD you could suggest that doesn't need that much code? Simple numeric 2rows would be enough. Want to use it with the nRF51-DK to display some measured valued...
I would like to develop my own central device to communicate with the RedBear Arduino shield. The RB device uses a from of UART communications to send data to/from Android...
I was wanting to use a nRF24L01 with a breadboard but its pin-out didn't allow it. A solution then occurred to me based on parts at hand. I wrote it up with instructions and...
Hello. Can I get a literature to the nRF51 series?
I need a full abstraction of the nRF51, like a book or other information, it's structure schematic of build-in modules...

Our company needs wireless temperature sensors (can be externally powered or battery operated) and transceiver with 4 channel analog outputs. It has to be finished product...
Dear all,
I am planning to develop a system which has the same functionality as N550M8CC SoC.
I cannot use directly N550M8CC module because space limitations so I am...
Hello everyone
I am trying to write to SDCARD with FATFS.
Data received from BLE and SAADC incoming data.
Writes every second.
The size is about 100 bytes.
SAADC is 1000...
Hi guys,
I wanted to try out the experimental "ble_app_att_mtu_throughput" on the newest nRF5240 DK. Using Keil, this project is to big for the free version. Since I knew...
Hi everyone,
I have one problem with the application timer. When I change the state of characteristic to the value of 1, the following code is executed:
err_code = app_timer_stop...
Just stumbled upon a few questions, which are hard for me to answer at the moment.
I wanted to do some throughput measurements with the example taken from SDK 14.2.0 mentioned...
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...
