In my experience, using printf adds 1K to the stack requirement for a task.

I am getting the same error again. Please help me to solve this issue.

Maybe it's hanging in your NVS calls at the end.

I think you would have to perform that on your product. Security is based on your specific implementation of the security features available to you in the platform. You can produce a product with the ESP32 that has no security if you want.

I'm guessing it should be right here.. C:/msys32/home/Administrator/esp/esp-idf/components/mqtt/esp-mqtt/include But I'm wondering why the IDF path to the project.mk is different than the one it's looking for that file. That is likely the clue to your problem. It may be that you are compiling a IDF ...

I'm doing this off the top of my head, but it should work..

typedef int arr2d[2];

arr2d myvar[] = {{11,12},{21,22},{31,32},{41,42},{51,52}};

or...

arr2d *myvar = {{11,12},{21,22},{31,32},{41,42},{51,52}};


void show (myvar *b,int l,int p);

esp_ota_set_boot_partition
Restart ESP32 with some timer mechanism of 5 seconds or 10 seconds

What's the point of the delay before reboot? I've been doing OTA without a delay before reboot and not sure if there is a potential problem.

I'm using IDF v3.1.3 and ran into a problem with esp_vfs_fat_spiflash_mount failing.... static const esp_vfs_fat_mount_config_t mount_config = { 10, // max_files true, //format_if_mount_failed CONFIG_WL_SECTOR_SIZE, // allocation_unit_size }; err = esp_vfs_fat_spiflash_mount(ffs_base_path, "storage"...

I may be beating a dead horse, but wifi performance in a busy office setting appears to be pretty bad. Hi John, Just to check all the variables: how is 2.4GHz WiFi performance for other devices in the same environment? ie if you connect a PC to the 2.4GHz network (ie same router, same frequency ban...
