Hello,
I have an app that uses BLE and WiFi. I required to allocate a large free block (size=115200). However, when I call to heap_caps_get_largest_free_block(MALLOC_CAP_DMA | MALLOC_CAP_32BIT)) I see that there is not enough largest free block memory (free size=110592). What could I do to free heap memory in order to get the suitable large free block?
␛[0;32mI (7378) hagl_esp_mipi: Largest (MALLOC_CAP_DMA | MALLOC_CAP_32BIT) block before init: 110592␛[0m
␛[0;32mI (7378) hagl_esp_mipi: Size required: 115200␛[0m
␛[0;31mE (7388) hagl_esp_mipi: NO BUFFER 1␛[0m
␛[0;32mI (7388) hagl_esp_mipi: Largest (MALLOC_CAP_DMA | MALLOC_CAP_32BIT) block after init: 110592␛[0m
