First time here? Check out the Tour!
Hi! i am thinking about cut off uart when data is not transmitting. As a method 1, i am thinking about using CTS and RTS Pin which is hardware flow control! ①Is this possible?? ②also,Is there a sample code ... (more)
I'm working with uart on the nrf52832 and I'm facing an issue related to the baudrate.
In this post a formula for calculating the baudrate given the register value is given. By applying that formula to the UART_BAUDRATE_BAUDRATE_Baud921600 ... (more)
I am using nRF52832 and softdevice is S132 adk13.1. My application is read 3 ADC channel one by one and send this value to android app using NUS. For this i have use This Time drive Adc exmple ... (more)
i would like to print register values of an external sensor on my screen using UART! I'm reading and writing into those registers using SPI! Printing a normal message using NRF_LOG_INFO function is fine, but how do i print ... (more)
I am facing some issue, I am using HM10 ble module as peripheral and NRF52832 (Redbear NANO v2) as central device. I using SDK "nRF5_SDK_12.3.0_d7731ad" and example program "nRF5_SDK_12.3.0_d7731ad\nRF5_SDK_12.3.0_d7731ad\examples\ble_central\ble_app_uart_c". I ... (more)
I have a sensor with serial protocol of 7 bits data, even parity, 2 stop bits. I wanted to use uart library to interface with this sensor. But I couldn't find the settings to change data bits, even/odd ... (more)
Hi, now I'm using NRF52832 's UART with SD12 and it required to receive 40 bytes per 10ms.
In fact, it does not take 10ms to complete the reception.So my idea is to create a 10ms timer task ... (more)
hi, i have set the uart buffer size as 64. but when i am transmitting data,i found that the size might not enough(eg. there are 100 Bytes to send).how could i do except for expanding the size ... (more)
I am running the ble_app_uart example in SDK 13.0 with nRF52382.
The app can receive data via UART only when I use "Termite" as a terminal emulator. If I use "TeraTerm", "Putty" and "RealTerm" to send data ... (more)
When P0.15 is held high, the nrf_cli fails to talk to my computer via serial. Lowering P0.15 allows all buffered bytes to be sent to my terminal.
Oddly, Pin 15 is not part of my UART CONFIG.
As ... (more)
I am trying to connect multiple BLE HC 08 devices to nRF52832 DK but I am not getting how to configure the nRF52832 as central
I have two NRF52 chip sets. Yesterday, I was able to build and flash the Beacon and UART sample projects onto both of these chipsets.
After building and flashing, a small blue LED light would start blinking periodically. I could ... (more)
Firstly, platform: Sparkfun 52832 breakout board, DFU using UART, flashing an application, using nrfutil.
The problem fundamentally is the nRF52832 is not sending an ack that it received the DFU start packet. The packet is formatted correctly as defined by ... (more)
I connected a Classic Bluetooth Device on my PC through by Bluetooth.
1-)I saw this message:
That means "Bluetooth Services Configuring"
2-)I saw this in device manager:
But, When I connected nRF52832 on my PC through by Bluetooth ... (more)
Hi, I'm using the UART to talk to a radio module with sdk 12.1 on nrf52.
I'm seeing frequent UART errors, where the event handler is called with event type APP_UART_COMMUNICATION_ERROR. Debugging in the UART0_IRQHandler() with this ... (more)
Hi, I'm learning to use the nrf52832 (PCA10040). I'm on SDK12.2.0 S132.
I've done those basic tutorials while merging codes from the examples. My code can currently read the die temperature and broadcast it via ... (more)
I would be interested on knowing whether I may have a secondary UART on the nrF52 chip or not. I would like to communicate my nRF52 with a RN2483 and this is done through UART, however I see that ... (more)
Hi, I have tested a sample code which sends some data through BLE in nRF52 development kit(PCA10400). The code is attached below.
I was able to connect the nRF UART app with the nRF DK ... (more)
