So I have a project that need ESP-01 (ESP8266) and Fingerprint Sensor (FM10A). Both of the component need to communicate from SoftwareSerial. For some project-related reason I can’t use the hardware-serial.
The programs works like this:
- The fingerprint sensor is going to capture a fingerprint and give it an ID (String)
- The ID is going to be sent to firebase database using ESP-01
Is it possible to make them work using 2 SoftwareSerial?
Any helpful response would be appreciated, thank you!
The ESP-01 (ESP8266)is only a WiFi module with 2 gpios available.
It should be used together with a micro-controller board and not stand alone.
Better is to get a micro-controller board like esp32.
