esp_http_client post failing to timeout in bad Wi-Fi

Postby BrettG » Mon Jan 27, 2020 4:52 pm

I am running into issues sending a post over a bad wireless network (network simply too far away for reliable transmission) where it sometimes gets stuck sending data to the server and does not timeout after 5 seconds as it has been setup in esp_http_client_init.

This test is currently running on esp-idf 3.3.1 but have had similar failures on 3.2.X. I have found that the larger the file being sent the more likely it is to get stuck. And when the transmission does get stuck it also does not trigger the watchdog as it is supposed to after a minute.

Given time the device may get out of this state, but it is expected to timeout properly.

In the example output below it shows the first two transmissions more or less failing properly, then on the third transmission it gets stuck after printing out the headers. I have also added a task to help show time elapsing after it gets stuck.

Re: esp_http_client post failing to timeout in bad Wi-Fi

Postby BrettG » Thu Jan 30, 2020 4:28 pm

I have tried using the esp_http_client_fetch_headers fix that was implemented in esp-idf 4.0rc and it reduced the issue slightly but is still occurring.

my understanding is that the timeout currently is set up to be the timeout for each small action of the larger transaction, rather than being the timeout for the transaction as a whole. unfortunately that does not work well for my purposes.

I have also tried using the is_async flag the client init with slight success. With the ability to call esp_http_client_perform asynchronously i can time it out manually, but it appears that after the first transaction the esp-tls is left in a bad state and all transactions afterwards using the same client handle fails with the message "esp-tls: invalid esp-tls state".

I am continuing to look into running esp_http_client_perform asynchronously and how to leave esp-tls in a usable state.
