Hello, I'm having a trouble over here, I read some tutorials for creating custom services and characteristics for BLE, and everything is running fine, I have a service with a characteristic that hold some text in hex (uint8_t), and I set the permissions to read/write that characteristic, now, i want to send a serial command over one of the GPIO ports, and I'm using the nRF52 DK so I'm using the P0.06 (TXD) and P0.08 (RXD), but I don't have a clue how to send the serial command to those GPIO ports, I need to send a command for a nextion TFT screen, to change a value, so I need to send a text first like (t0.val="test") and then 0xFF three times so the screen will read the commands.
How do I do that on the nRF52832?, I saw a UART example on the SDK but I cannot understand it very well, I don't want to establish a deep connection, just send some commands, and I might also point that I'm a beginner on C programming.
