GT511C3 Fingerprint sensor with ESP8266 and FreeRTOS

[licondam]

Hi, I want to use GT511C3 with ESP8266 using FreeRTOS, as there is no existing driver, I am trying to write one. What I am facing problem in, is the Serial communication with the Sensor. The Sensor has a Rx and Tx pins for serial comm(I am guessing UART), I looked at its library in Arduino driver for this sensor and they are using SoftareSerial.h for serial read/write operations. I need to send a command packet of 12 bytes and then receive a response packet of 12 bytes. I tried sending the data byte by byte using putchar and recieve using getchar but I didn't receive any response. So basically i need to create something like a softwareserial.h in esp-open-rtos. Any Help?

I can assist you. I've used both hardware and software uart on the esp8266. What timezone are you?
I use NONOS SDK but if I take a look at your setup I may still be able to point you in the right direction.
Why do you feel you require you use a Software Serial over your hardware Serial.. Your Hardware implementation should be fine to use to talk to the scanner.
