I'm trying to use the LPCOMP of the nrf52 telit board.Configured lpcomp with the following settings :
Input : AIN2 Ref : AIN1 ( external ref. of 1.6V) Detection : Crossing
I've initialised the lpcomp and enabled the lpcomp with ... (more)
I am reading a large FIFO buffer from a sensor and there are at least two ways to do it - by simply reading the FIFO using the CPU and SPI in chunks of 255 byte blocks, or using EasyDma list ... (more)
i am working with SDK 14 type 4 tag library on NRF52832 hardware. I've based my code on the example "writable ndef msg".
When receiving a record, the NFC handler assumes, that NLEN is first updated to 0 ... (more)
I am trying to record data from ADC to a SD card every 500ms using nrf52832. I am following the fatfs example. Before I had a problem whereby every approximately 10s I would lose a few samples from ... (more)

is there any documentation about DFU init file structure (SDK 14.0)? I used NRF util for creating DFU package, but i want to create my own app for that purpose.
Hi all , I using module NRF52832 and SDKv14 . I have 2 board central and 2 board peripheral . I want to connect each board central to all board peripheral and connect each board peripheral to all board central . Pls give me ... (more)
I'm trying to build a generator based on NRF52832. Outpit signals are: 8MHz clock and two latches signals highly sinchronized with clock - RGB_LAT and TXT_LAT. For this task I used TIMER1, PPI and GPIOTE. Actually my approach ... (more)
I have a question on how to calculate the capacitance based on oscillator relaxation for NRF52. For example, in the Csense_drv example, when pin is touched by finger, it generates digits (e.g. 850). My question is how I ... (more)
The softdevice is initialized as in the BLE UART example. The body of the
ble_stack_init() function is identical to the BLE UART example.
SPI is initialized as in the SPI peripheral example, but I have gone over to writing ... (more)
I am working on pca10040, nrf52832 and s132. I am using ble_app_uart and sd card, where i want to transmit data received over ble to the sd card.
Can you help me with how can i do so ... (more)
I can read the rssi value after the connection is established.
case BLE_GAP_EVT_CONNECTED: APPL_LOG("Connected to target\r\n"); err_code = bsp_indication_set(BSP_INDICATE_CONNECTED); APP_ERROR_CHECK(err_code); m_ble_nus_c.conn_handle = p_ble_evt->evt.gap_evt.conn_handle; // start discovery of services. The NUS Client waits for ...
I have an application based on ble_app_hrs_freertos from SDK14. Sometimes the application will not start advertising. When this happens, it does not help to power-cycle device. Sometimes it helps to reset the device with nRFgo Studio, simply to let it ... (more)
I'm wondering if I can get current transmitting channel during a connection. So 1. Is there a way I can directly read current transmitting channel? 2. If not, is it possible to know the hopIncrement for current connection ... (more)
Hi all , I have one question . I have 3 board NRF : 1 peripheral and 2 central board . I want to transmiss data from peripheral board to central board 1 then from central board 1 to central board 2 . I want ... (more)
I want to use in my project tft 1.8 display with st7735 controller. I'd like to use some based code but can find nothing except on infocenter nordic As I understand there are should be something to be ... (more)
I am having trouble running softdevice_enable. Here is what happens:
After main(void) starts the code is:
log_init(); // WORKS clock_init(); // WORKS buttons_leds_init(&erase_bonds); // WORKS ble_stack_init(); // FAILURE results in infinite resets due to a weak error callback.
ble_stack_init is boilerplate code ... (more)
I am using the dfu\bootloader_secure_ble example as my starting point. My goal is to create a very simple bootloader (with none of the dfu stuff, no SD functionality). Just a simple bootloader that the MBR ... (more)
I am writing a boot loader which does not need to use the soft device as the image is being transferred over an SPI interface.
I have merged the softdevice and my application code together to make a single ... (more)
I have two supplier for provide me nrf52832's based modules. So I tested it and both is ok. The distance used pcb antenna almost the same (about 80m).
If I use on external antenna with gain 3dbi I got ... (more)
I'm building a project with nRF52832 dev kit and the SHT10 temperature and humidity sensor, I'm searching for a library/example project of this sensor and the nRF52. So far I didn't find one, are you ... (more)
