I have an Arduino UNO and HC-05, fixedly connected and working properly. Wiring: 5V, GND, Rx->Tx, Tx->Rx.
I want to program via Bluetooth.
However, the HC-05 State and UNO Reset pins were not connected and I can no longer do this.
Is there a way to software reset the UNO when the program starts uploading via Bluetooth?
If I press the UNO Reset button at the start of uploading, the program will upload. This is what I want to achieve in software. Can it be solved?
There is an external push button connected to PIN 7, I can press it and use it to start the resetFun() function, it also resets the UNO, but it still doesn't work properly and the upload fails?
Post your sketch, well formated, with well-tempered comments and in so called code tags "< code >" and a detailed circuit diagram to see how we can help.
This is a copy of the original power stone, I can test it.
When start the Programing via Arduino IDE, and the PIN7 connect to GND, UNO reset OK, but the program uploading failed. If i push the UNO Reset button instead of PIN7 -to GND, the uploading successfully.
