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 :
the once connect: error code 0x7A cann't read characteristic and 0x14 state change.
the second...
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...
I am toggling Value of slave through a button on nrf51822ek .This Value is displayed on MCP of dongle, but i have to get this value on terminal to send it to pi then through...
Hello, I am tryong to use to masters to communicate with two accelerometers.
Q1_ I found the following image from Nordic's website that shows SPI0 pins but there is no indication...
Hi, I have modified the twi_scanner example of the 52840 DK to be compatible with nRFDongle.
I fully erased the dongle with Segger and passed the new hex file with SWD cable...
I used NRF connect to connect to a slave。
I want to use the central to connect to the device。
this is my code.
but the service is not found。
static void...
We are developing a platform that can have multiple configurations, with or without softdevice/ble, with or without bootloader (for upgrading), both on nrf52832 and nrf52840...
Hello,
I'm using the nRF9160DK (PCA10090 0.8.2). I was able to see the data coming from the nRF9160DK in the nrfcloud, but now I want to be able to see the data published...
Hi,
I'm working on nrf52832 NUS. When i connect to device with "nrf connect app" i can see the data coming from sensor. But few seconds later device disconnect.
When...
Hi,
To build the context: I have two peripherals, Sensor 1 and Sensor 2. Sensor 1 has been running off of a NUS service to transmit data. Sensor 2 has been running off of...
Hi all,
I make a key using nrf52832. It tranfer data to other device. I have 2 option for this. Using beacon (BLE) or Enhanced ShockBurst (ESB) . I want to optimize energy...
Hi all.
In our project we are using BLE, but at some point switch to ESB. The code below disables the SD, and sets up ESB which is then used from then on.
This all...
Hi,
I am using nRF52 DK PCA10040 to develop an application starting from the ble_app_uart example, Then I introduced PWM and SAADC from other examples, and after I verified...
I have an nRF91 DK v0.7.0 which I'm using for the first time with a Hologram.io SIM card and nothing seems to be working. Nordic sales and an FAE were here in late February...
Hello,
I need to get nrf9160 to connect to a LTE-M network. We are using a custom pcb module with nrf91 on it. I've managed to get a simple hello world, blinky and gps simulator...
Hi,
I am currently working on a project in Mesh on nRF52840 DK.
I am using the mesh v3.1.0.
I wanted to send command from mobile app to particular node in the mesh and...
Hi, i use the saadc example(triggered by ppi+timer) with uart to get voltage signal and transmit to central device( another custom nrf52832 board), and the central prints...
I am using SPI communication to transfer data from an ADC (ADS1220) to my nrf52382, then to the mobile app via bluetooth. The ADC is the slave. The NRF is the master. So MISO...
