I just unbox my brand new Wireless Stick Lite and upload GetChipID code in Arduino IDE , Board " Heltec Wireless Stick" was selected. Upload done sucessfully !

From Serial Monitor , there is no Chip ID display , but below message shown instead

You should select the Heltec “Wireless Stick Lite” board in the Arduino IDE.

Hi,

I am all setup and the heltec wireless stick worked fine the first time around. I uploaded the code I am using for a air emissions test. Now I am trying to clear and upload factory test or any other file to the board and keep getting the same error

have the baudrate to 115200 and the correct board selected… seems like something is not right with the board. I have exchanged using different usb ports and cables. tested on esp32 dev kit and works fine. I purchased from a reseller on amazon, i am looking for a exchange unless someone can instruct on whats wrong and what is fix…
