CC3220S: Cannot manage to get all the data from Github repository through the CC3220S using the SimpleLink Cloud-OTA example.

Part Number: CC3220S

Hi,

I am using the CC3220S LaunchXL development board with the SimpleLink 32xx SDK 3_10_00_04:

I have configured the code as per requirements and it is as follows:

#define OTA_SERVER_TYPE OTA_SERVER_GITHUB

/* OTA server info */
/* --------------- */

#define OTA_VENDOR_DIR ""

#if OTA_SERVER_TYPE == OTA_SERVER_GITHUB

/* Github server info */
#define OTA_SERVER_NAME "api.github.com"
#define OTA_SERVER_IP_ADDRESS 0x00000000
#define OTA_SERVER_SECURED 1

/* Github vendor info */
#define OTA_VENDOR_ROOT_DIR "/repos/Noel-Altro/OTA_test" //"/repos/<user account>/<user directory>"
#define OTA_VENDOR_TOKEN "02d75cd51e0d4b5ea3c**********5cc9d0158ea"

#define OTA_SERVER_ROOT_CA_CERT "digcert_high_assurance_ca.cer"
#define OTA_SERVER_AUTH_IGNORE_DATA_TIME_ERRORs
#define OTA_SERVER_AUTH_DISABLE_CERT_STORE

I have managed to connect to the server via this code but I am getting only Partial data, not the entire amount.

The following is the debug output:

Could you look into it and let me know what the issue can be. 

Thank you ,

Noel.

    Hi,

    Thanks for the reply, it solved my issue.

    But I have faced another issue further on, which when I tweaked the code solved the issue.

    Initially I had uploaded the .tar file onto a public repository on github which worked flawlessly after doing the recommended correction through your previous reply.

    But when I changed the github  repository to private, I faced the issue of HTTP ERROR 404. Using Postman I tried querying the issue using the token provided by github, I was successful and noticed that the HTTP request sent by it included a Authentication parameter.

    So I made the required changes onto the code in the CdnGithub.c file as follows and it worked.

    #define OTA_SERVER_REST_HDR             "User-Agent: Altro\r\nAuthorization: Bearer "

    I wanted to know if there is a provision to overcome my issue in the SDK itself rather than tweaking it the way I have done.

    Noel.

    Hi Noel,

    Thanks for the info. This looks like the right way to handle this.

    We'll check this internally and probably update the SDK.

    Currently, I can't commit to the exact date.

    Thanks,

    Kobi
