Hi @david.king,
I am successful in upgrading HL7692 via dwl using teratern. Below the steps that I did
-Download teraterm file here
- Extract zip file then open ttermpro.exe
- Open serial port
- Send : AT+WDSI=4095
- Define the size of dwl file: at+wdsd=20304768. (This number is the size of file. You can see below)
- Select <Transfer> then <Send File>. Select rev.dwl and 1K Xmodem, then click Send. It starts transferring the file. It takes about 15 minutes to complete transfer process
OK
+WDSI: 3 /// It means a package is ready to install
