1 year ago First, although this does somewhat work on ESP32, it was designed for ESP8266 and I don't use it there. I have a different client for ESP32 because with FreeRTOS async is not really needed as the operation can be done asynchronously using a FreeRTOS task.
Back to your problem, the problem is probably in buffering the response. If you make use of the ONDATA callback to take the data as it comes in you shoud be able to handle larger responses.
In IoTaWatt, I receive a megabyte response, writing it to an SDcard.
Hello, I find it works pretty good when server's response content size is not very big, but when request a content larger than 5KB, that is 5.78KB, it will crash always.
I read the readme again, noticed you have mentioned this, "Single String response for short (<~5K) responses (heap permitting)." I wonder is it possible to achive this goal?
Here's the backtrace, I have tried different arduino-frameworks, the same result, I doubt it is a heap related issue, but have no idea after digger for two days.
Any help will be appreciated!!!
