OTA failing (Unable to request firmware chunk) about thingsboard-client-sdk

[pablo18393]

Hello @MathewHDYT ,
thank you for the detailed explanation, it is very helpful.
I defined the OTA callback as you said, the issue is no longer happening (I tried 20 times with no issues).
Have a Merry Christmas.

The re-connection attempts are not made by the library, but in the aforementioned example the re-connection attempts have to be made by the user utilizing the library.

In the case of the example it is the main method which reconnects. This is the case because reconnecting is different for every device and reconnecting directly in the library would be very hard and bug prone to implement and not really have a real advantage.

For now would it be possible to adjust the internal timeout in the OTA_Callback .

const OTA_Update_Callback callback(&progressCallback, &updatedCallback, CURRENT_FIRMWARE_TITLE, CURRENT_FIRMWARE_VERSION, &updater, 20, FIRMWARE_PACKET_SIZE, 10U * 1000U * 1000U);

This will wait 10 seconds between each rerequest of the same chunk if it failed and attempts to download the same chunk 20 times.

While that is happening ensure that the connection is attempted, if you are using the example it should print Connecting to: demo.thingsboard with token.
