I am using HL7650 module.I am trying to write the key using AT+KCERTSTORE=0,1294,0
Unfortunately its throwing error 931.Would any one suggest me what is wrong in it.
Hi @jagadeesh.kumar,
931- means “The length of a parameter is invalid”. Please check the length of the root key. I did a quick check on the key that you provided and it is more than 1294 bytes. Assuming the root key is provided correctly, the length appears to be 1488 bytes.
Please first confirm the file size is 1294? or 1590?
Make sure no CR/LF is added or changed during the transmition.
If you use the Teraterm tool, you can to send the cert with “File->sendFile->Binary”. “Binary” is mandotory.
Also, hardware flow control should be enabled in Tertaterm side.
Since the length is specified in +KCERTSTORE, then no need to send +++ to exit data mode of +KCERTSTORE.
Here’s my good result:
AT+KCERTSTORE=0,1590,0
CONNECT
//Send 1590 bytes of file.
OK
AT+KCERTSTORE?
+KCERTSTORE:
root_cert,0,1590
