Hello
I ran into a problem which i tried to investigate in the last week.
I'm using an ESP8266, wemos D1mini, and was able to reproduce the crash using the PhotoFromURL example.
This submitted issue might probably be a dublicate of #51 and #52 . Feel free to move and modify my post in any way you see fit.
Also note that this issue might be caused by ArduinoJSON or another library which Universal-Arduino-atelegram-Bot relies upon.
The crash occurs when sending messages. In my project the ESP crashes after sending 2-5 messages. Using the unmodified PhotoFromURL example it takes about 100-300 messages within ~3 minutes, which resulted in an Exception (29) crash.
I slightly modified the example and filled the RAM with a big global char array and wrote ESP.GetFreeHeap() to the serial output, which triggers the crash after sending ~10 messages.
The exception always occurs when the free heap size decreses beneath ~6500-5700.
The free heap size increases automatically when ~3min have passed. I assume the old buffers or something gets deleted when they are older than ~3min. The RAM gets filled the fastest when alternating between different messages, using my sketch: /get_test_photo and /status .
I enabled the _debug bool in UniversalTelegramBot.h
This is the modified sketch:
telegram_exceptionist.zip
Here 3 possible combinations and their outcome:
telegram_exeptionist.ino using WiFiClientSecure without filling RAM (no char array):
Sketch uses 296285 bytes (28%) of program storage space. Maximum is 1044464 bytes.
Global variables use 40484 bytes (49%) of dynamic memory, leaving 41436 bytes for local variables. Maximum is 81920 bytes.

free heaps:
at start 17300 B
crashes after 6160 B
(this was almost impossible since 100-300 messages have to be sent, but the RAM starts to free up again after ~3min.)

wdt reset
Notes
when the ESP crashes and dumps its stack, it waits 3s until the last line "wdt reset" happens.
i installed and tried the Arduino ESP8266/ESP32 Exception Stack Trace Decoder with an interesting first line. Apart from that i'm not sure what to look for..
The decoded output: [expand]
Exception 29: StoreProhibited: A store referenced a page mapped with an attribute that does not permit stores

Build options:
Board: "Wemos D1 R2 & mini"
CPU Frequency: "80MHz"
Flash Size: "4M (3M SPIFFS)"
Upload Speed: "921600"
Other things i've tried:
Different USB Power adapter. no effect.
I got the same crash on another ESP8266, with different power adapter and cable.
470uF Capacitor is in place on the 5V rail.
Added a 2200uF Capacitor to the 3.3V rail. no effect.
changed to 1M flash size. no effect.
changed clock to 160mhz. no effect.
If anyone has a clue on how to resolve this issue, or an idea on what to try next, let me know.
Best regards,
dejan lauber
PS: The ESP8266 and this telegram library blew my mind! Awesome work!
