If bluduino applied to the hope that more areas will suggest one thing .
If possible , you must pass through a password when uploading sketch program can be used widely in the field of security blueduino
Please save with a password to prevent anyone upload sw blueduino … Through the AT command
Can you security firmware upgrade?
BlueDuino is based on ATMega32U4. It has a virtual serial port for uploading sketch. It’s difficult to uploading sketch by BLE.
We suggest use USB to UART converter (3.3V) to upgrade firmware.
This concept is not suggesting to use upload ble.
only possible to pass through using upload password when you upload by usb.
not firmware … when sketch up program uploaded… use password
what do you think about it ?.
I got your point. You hope there’s a password when someone upload sketch by usb.
I’ll check it.
ok you got it !!
I’ll wait for your response . thanks ~
There’s no a good solution for prevent uploading sketch by password. What about some minor change for hardware?
For example, you can remove two resistors for USB after you uploaded sketch. Here’s a photo for the two resistors.
I got your concept… but hardware changing method can not have effect by recovering method ~
anybody can read articles this by Web Forum …
also when upgrade changed skech program , this method Not easy
Is there a better way??
