Topic: 2 Arduinos connection with HC-05 and RX/TX (Read 119 times) previous topic - next topic


we' re having a problem with the communication Arduino UNO that we' re using already. HC-05 bluetooth module is connected with the master Arduino. Master one has bluetooth already and we' re sending bluetooth data to the other one. We are connected Rx and TX pins with serial connection. The problem is none of our datas reach one the slave. What can I do?


What can I do?
One thing you can do is give a better description of the project, particularly the wiring.  Have you connected Tx>Rx and Rx>Tx?


Thank you. I will try. But RX connected TX.
