I am trying to transferAdvertisement data from NRF52832 to Raspberry PI using BLE_app_UART example. I have updated the config as below,
app_uart_comm_params_t const comm_params =
{
.rx_pin_no = 3,
.tx_pin_no = 2,
.rts_pin_no = 17,
.cts_pin_no = 18,
.flow_control = APP_UART_FLOW_CONTROL_DISABLED,
.use_parity = false,
.baud_rate = UART_BAUDRATE_BAUDRATE_Baud115200
};
I have wired as below
NRF52832 ------ Raspberry Pi
rx_pin_no 3 ----- GPIO14(UART_TXD0)
tx_pin_no 2 ----- GPIO15(UART_RXD0)
rts_pin_no 17 ------- GPIO 16
cts_pin_no 18 ------ GPIO 17
GND ----- GND
After this connection if I run the below Python code in Raspberry PI, I am getting invalid characters printed and reading after 1 byte getting error as 'Serial port is not ready'.
import serial
from time import sleep
ser = serial.Serial ("/dev/ttyS0", 115200) #Open port with baud rate
while True:
received_data = ser.read() #read serial port
sleep(0.03)
data_left = ser.inWaiting() #check for remaining byte
received_data += ser.read(data_left)
print (received_data) #print received data
Please help if have missed any thing in the connection between Raspberry and NRF52832 or config.
