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...
hts, HTC phone, nrf tools HTM, nrf51822,
every time when it's power up :

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...
Hi,
I am using the USB CDC example in my project, where I developed my own application level communication protocol.
I have a problem with the data throughput, it's...
I am designing a custom board with a nRF52840 module that has no 32.768 kHz crystal embedded in it and as a first step want to test it with some examples that use only RC...
Hi all,
I'm trying to setup an interrupt-driven UART. UART is able to transmit data, but I don't get the TXRDY interrupt.
Below is my minimal initialisation that outputs...
I developed on sdk16.0 and found that app_button has abnormal power consumption,
so I replaced it with app_button of sdk15.3, but found that no key events were reported...
I want to use UARTE to handle terminal style messages. That is, messages are ended with a newline, I have absolutely no idea how long they will be, and the delay between multiple...
Hi there, Just wondering how to get the comparator "RESULT" (not part of EVENT) onto an output pin without CPU intervention. From the datasheet I believe: 1. the RESULT is...
I am a newbie with nordic, where I have recently purchased the nrf52810 device. I need some guidelines to get started. My intention is to read data via TWI from an MPU6050...
Hi,
In past we have observed BLE_HCI_LOCAL_HOST_TERMINATED_CONNECTION as a disconnection reason when the application layer tries to disconnect because of a timeout. But...
Hello, we are developing a project solution where we want to pass data between multiple sensor devices using BLE advertising data. For now, we have a test setup with two nrf52832dk...
Hi,
I would like to catch in main.c the nobody connect after advertising event via ADV_SET_TERMINATED.
I can see with breakpoint program jump into ble_advertising_on_ble_evt...
Hello
I am making a button double-click function in sdk v17. I've tried 'app_button' and 'app_timer'. Created a timer that is called every 0.1 seconds and terminates when...
Hi there,
To put a little bit of context, I've designed a wearable that is now going towards pre-production (only some minors fix left to do). In the last iteration, we...
Hi,all:
I use 9160DK to test PSM mode as follow steps with at_client example:
1、set ”AT+CFUN=0“ to power off mode;
2、set "AT+CPSMS=1,"","","10101010","00100001"" to...
Hello,
We're making RuuviTag sensor beacons which log environmental data to flash. Logged data is later read by a mobile phone application over Nordic UART Service.
The...
Hello
I am programming using the nrf52832 module 'MDBT42Q-512KV2' in SDK v17.0.
This works well without any problems in the example ble_app_blink. However, the BLE is...
