SoftwareSerial Alternatives ( to use with HC-05 bluetooth module )


I am working on a school project where i need to connect three bluetooth devices ( HC-05 ) to my arduino uno.

I tried using the library SoftwareSerial but it doesn't seem to work due to the limitation of one device active at a time.

I know that an arduino mega has 4 serial entities but i'm prohibated to use it...

Is there any alternative to softwareserial where all my devices can be active at the same time ? or can anyone advice on how to connect three bluetooth devices to an arduino uno.


Best regards
