[SOLVED] BLE and Wifi = out of memory ??

[chegewara]

Hi,
could you provide some logs with error? Also what environment are you using, esp-idf or arduino-ide?

[anandvilayil]

thank you for considering me,

i am using esp-idf,
and the log showing is,

What http server do you actually use, by the way?

[anandvilayil]

added libesphttpd in to espidf and working on it

[anandvilayil]

sir,
problem is occurred due to initializing and enabling bluetooth controller and bluedroid. if i command that lines and running the program, the server runs correctly. why so?

some logs are below,

Well, the BT controller uses up some memory, so enabling ity may just tip you over the edge. Suggest you take a deep look at the memory usage of your app and see if you can save some bytes somewhere. Alternatively, see if you can change over to an ESP-Wrover or something, so you can use the 4MiB PSRAM it has.

[anandvilayil]

i am using ESP_32 wrover.

[anandvilayil]

thanks you for your valuable time,
the problem is solved. its because of over consumption of memory while mallocing @ server creation.
