MC60 AWS Certificate using AT+QSECWRITE

IoT Modules GSM Module

Hi,
Please find the attached files.
files.zip (7.8 KB)

Sample certificates are defined in alua_gsmMqtt.h file. Refer other C files how is copied and sent to module. Sorry to say, do not have that much time to explain in details and can’t share the project as whole. In shortcut open in notepad and trace function calling flow. alua_miscConv16bToDecAscii() is a crucial function.

It needs conversion from ASCII certificate to hex… refer the code attached.

Please attempt and let me know your success, will be happy to know.

regards
PK Jena
