Hi all,
I am using nRF82532 board. This board TX,RX(P0.06,p.0.08) pins connected with QUECTEL module in ZEPHYR sdk platform . Please forgive me for these basic doubts.
1. If I need to send some command from my nRF52832 board to QUECTEL module through UART, how can I make communication through UART?
2.How do I configure UART using ZEPHYR API's?
Have you looked at the examples in the SDK ?

As always, the way to start this kind of project is to get the UART talking to a terminal on a PC
Once you have that working, then - and only then - move on to getting it to work with the Quectel.
Similarly, you should also familiarise yourself with the Quectel by using it with a terminal on a PC
Hi,
What board do you use? Nordic DK or custom?
UART is configured basing on:
1. board's device tree - this is where you define PINs, baudrate and peripheral (UART/UARTE - using compatible)
2. Kconfig - this is where you select driver (UART or UARTE). You need to ensure that peripheral in DT (device tree) and selected driver are consistent.
3. prj.conf file - this is where you say that your project is willing to use UART feature.
Next when you are in the main function all is ready and initialized. UART API is located in the file:
zephyr\include\uart.h
Hi Sir,
I am using Nordic DK board.
1. Generate hello world example: zephyr/samples/hello_world
2. edit main.c file. It shall look like that:

#include <zephyr.h>
#include <misc/printk.h>
#include <uart.h>
void main(void)
{
struct device *dev =
device_get_binding(DT_UART_CONSOLE_ON_DEV_NAME);
printk("Hello World! %s\n", CONFIG_BOARD);
uart_poll_out(dev, 'A'); // this is how you poll out raw data via uart
}
