It's fixed that multi_heap_free failed like below. It sometimes happen when esp32 recevied ble data fast from another device so I added semaphore so It was fixed.
assertion "head != NULL" failed: file "/Users/ficeto/Desktop/ESP32/ESP32/esp-idf-public/components/heap/multi_heap_poisoning.c", line 214, function: multi_heap_free
