My sensor is off-standard,so I have to use gpio to read and write my sensor.
Gpio IIC will take about 0.5ms to get data.
My app need send data every 7.5ms,it seems that...
Hi,
My android Proximity application fails on service discovery only for the very first time it connects with the devices(nrf51822 evaluation kit with sdk 5.2.0). Actually...
Has anyone converted the app note AN34 DTM Python script to C# or C/C++ ?
The Python DTM script is works OK with the setup specified in the app note AN34 figure 2, which...
Hi,
I have a serious problem, when I use uart of NRF51822 QFAAC0 to receive data from another MCU, I found that it will lost one bit at same position everytime. my SDK is...
Hi,
I just started to interface the lcd display with nrf51822 evaluation board. The display i'm using is, spi compatible, 18" tft (160x130) from tiny lcd. I took spi master...
Hi,
We are using the nRF905 device in an application where it needs to switch between auto-retransmitting and sending single packets, due to it communicating with several...
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...
Hi,
I am trying to read data via an ADC through SPI and send it via Bluetooth to the NRF mobile app. I checked that both the original BLE_UART example and the SPI master...
My SPI data transfer from a peripheral ADC works fine in the SPI example project. The same code doesn't transfer data properly when it is added in either a ble_template or...
Does the BLE NUS service use pins on the NRF? I'm using a custom made nrf52382 pcb where I transfer data from an ADC (ADS1220) via bluetooth to the nrf Toolbox app. But using...

Hi Everyone,
I'm new to nRF52832 programming. I want to learn more about nRF52 programs.
