LTETLSClient on Arduino

[mithun]

Hi,
I have been following LteHttpSecureClient example. I verified Truphone SIM works and obtaining IP address. I was successful to run LteWebClient example and also was successful to connect to test.mosquitto.com. But I am not able to run LteHttpSecureClient which is based on LTETLSClient. Code is stuck at client.get(getPath); . I am using V2.5.1 of Spresense. I even tried to downgrade but same result. I also verified Amazon root certificate is downloaded and copied to SD card properly. There must be something which I am missing but can't figure out. Can anyone please help?

Hello, @mithun

Sony just released a new firmware update tool. It works to update the LTE board from version RK_03_00_00_00_04121_001 to the most recent version RK_03_00_00_22_13151_002. We recommend updating the firmware and checking again to see if it solves any of the connection issues.

This is the link: https://developer.sony.com/develop/spresense/downloads/lte_downloads/lte_fwuptool-2/

To find out the version of the firmware, you can run the Arduino Example LteTestModem.

Please run this update and let me know if anything changes for you.

Hi @CamilaSouza ,

I am glad to report that new firmware update did the trick. I am able to connect to AWS MQTT over LTS. Thank you so much! Now I can eliminate the MQTT bridge I created earlier to bridge between AWS and LTE board.
