After giving AT+QDOWNLOAD , I am not able to get DIAG port to update firmware for opencpu
Yes, you can pulling up USB_BOOT pin to.
or use AT+QDOWNLOAD=1 command
I am doing the same thing but diag port is not available to update firmware . it only show serial device port.
@lyman-Q yes i know, but diag port is not valid after at+qdownload command
Can your module start up normally? If not, you need to pull up the USB_BOOT pin
@lyman-Q module is working normally .but after at+qdownload it is Showing only one port
After entering the download mode, there is only one download port. After restarting, the port will return to normal.
@lyman-Q after entering the download mode , I am getting a wrong port for firmware update .
Can you give me a screenshot of the question? It’s not clear from the description.
@lyman-Q i am not getting diag port for firmware update
To get the diag port, you need to run AT+QDOWNLOAD=1 using the USB port.
@lyman-Q after running AT+QDOWNLOAD=1 . i am not getting diag port
I mean you need to use the USB port so that you can get the diag port by executing AT+QDOWNLOAD=1.
@lyman-Q yes, so please guide on this.
