Hi, friends. When I integration CELLULAR API WITH FreeRTOS 2021.07, I have found the SecureSocket abstraction library (202007, Branches->feature/cellular) does not work, anybody can help me? thank you.

here is the log of secure socket library output: (blocked at the end)

Hi @eelaix , so you are trying to integrate the code here https://github.com/aws/amazon-freertos/tree/feature/cellular/libraries/abstractions/cellular into the amazon-freeROTS 2021.07? Let me check with my team and find someone can answer your question on the cellular integration.

Hi @eelaix , so you are trying to integrate the code here https://github.com/aws/amazon-freertos/tree/feature/cellular/libraries/abstractions/cellular into the amazon-freeROTS 2021.07? Let me check with my team and find someone can answer your question on the cellular integration.

yes, I am using these files:

[CELLULAR API] https://github.com/aws/amazon-freertos/tree/feature/cellular/libraries/abstractions/cellular/include

[COMMON 3GPP API] https://github.com/aws/amazon-freertos/tree/feature/cellular/vendors/aws/modules/3gpp/ports/cellular

[SPECIAL DRIVER] https://github.com/aws/amazon-freertos/tree/feature/cellular/vendors/quectel/modules/bg96/ports/cellular

[SecureSocket Library] https://github.com/aws/amazon-freertos/tree/feature/cellular/libraries/abstractions/secure_sockets/cellular

when I integrate these codes(2020.07) into amazon-freeRTOS 2021.07 everything worked fine except secure socket library.

Hi eelaix,

Thank you for your interest in feature cellular. Further development of cellular project is moved to the following repositories. https://github.com/FreeRTOS/Lab-Project-FreeRTOS-Cellular-Demo https://github.com/FreeRTOS/Lab-Project-FreeRTOS-Cellular-Library We suggest you reference these repositories for new updates.

The supported boards and cellular modules combinations in feature/cellular are listed below.

windows PC + quectel bg96
windows PC + sierra wireless hl7802
windows PC + ublox sara-r4
st stm32l475_discovery + quectel bg96
sierra wireless sensorhub + hl7802

From your first and second log, it looks like the log stop in mbedtls handshaking. I suggest you use windows PC + your modem for comparision with your hardware device.

Please reference the https://docs.aws.amazon.com/freertos/latest/userguide/getting_started_windows.html to setup windows device simulator.

To enable cellular modem with windows device simulator, apply following steps.

Add the following entry in cmake-gui BOARD_HAS_CELLULAR : to enable board cellular module setup Name : BOARD_HAS_CELLULAR Type : BOOL Value : SELECT Description : (Optional) SECURE_SOCKETS_CELLULAR : to use secure sockets cellular Name : SECURE_SOCKETS_CELLULAR Type : BOOL Value : SELECT Description : (Optional)
Select your cellular module in vendors/pc/boards/windows/CMakeLists.txt Change this line if your modem is not quectel bg96. include("${AFR_VENDORS_DIR}/quectel/modules/bg96/CMakeLists.txt")

Select the democonfigNETWORK_TYPES in vendors/pc/boards/windows/aws_demos/config_files/aws_demo_config.h

-#define democonfigNETWORK_TYPES                        ( AWSIOT_NETWORK_TYPE_ETH )
+#define democonfigNETWORK_TYPES                        ( AWSIOT_NETWORK_TYPE_CELLULAR )

Select the supported and enable network in vendors/pc/boards/windows/aws_demos/config_files/aws_iot_network_config.h


-#define configSUPPORTED_NETWORKS    ( AWSIOT_NETWORK_TYPE_ETH )
+#define configSUPPORTED_NETWORKS    ( AWSIOT_NETWORK_TYPE_ETH | AWSIOT_NETWORK_TYPE_CELLULAR )

-#define configENABLED_NETWORKS ( AWSIOT_NETWORK_TYPE_ETH ) +#define configENABLED_NETWORKS ( AWSIOT_NETWORK_TYPE_ETH | AWSIOT_NETWORK_TYPE_CELLULAR )


5. Select the com port of your cellular modem on PC in vendors/pc/boards/windows/aws_demos/config_files/aws_cellular_config.h

+#define cellularconfigCOMM_INTERFACE_PORT ""

6. Setup cellular APN and other config in demos/include/aws_cellular_demo.h

define configCELLULAR_APN ""


7. (optional) In case you don't use ethernet on your PC, you can apply the following patch to skip ethernet setup.

- DEMO_RUNNER_RunDemos();

The second suggestion is to enable the cellular debug log. Apply the following patch to enable cellular debug log.
