Unstable connection via GSM network. The signal quality is strong enough.

Open woodlist opened this issue 4 years ago • 3 comments

Describe the bug The code is fine tuned, everything works, but the performance of SSL engine is not stable. Particularly, when the internet traffic is absent, the SSL engine goes stuck. The attached video shows the local terminal and the Telegram bot performance. Even having terminal data showing that the connection is lost, Telegram bot commands are able to reach to controller.

To Reproduce NONE

Expected behavior A clear and concise description of what you expected to happen. A reproducible sketch is especially helpful.

i believe that this type of problem is due the low memory stack in sim800, i have put a sim7000g working in same code, that i have been using in sim868 with high data size package to AWS, 4G mode it had not encounter this type of problem not a single time in 1 hour of operation.

Upon newest Arduino IDE upgrade the compilation gives C:\Users\user\Documents\Arduino\libraries\SSLClient\src\SSLClientParameters.cpp: In function 'void std::__throw_length_error(const char*)': C:\Users\user\Documents\Arduino\libraries\SSLClient\src\SSLClientParameters.cpp:5:67: warning: 'noreturn' function does return void __attribute__((weak)) __throw_length_error(char const*) {} Compared with earlier Arduino 8.16 IDE, global variables used memory has been dropped down dramatically. Seems IDE developers have too much hard work done.

Yup those warnings are fine, they are an artifact of a hack that allows vectors to be used on older versions of the arduino core.
