Hello everyone,
I would like to insert a system on esp32 where, with my Android smartphone, I can share a file from the settings without using an app. Is there an example or a guide to follow? I couldn't find anything by googling.

Hello everybody, I need some advice on choosing the best way: I have 4kb (it's a structure) of data that needs to be stored permanently and sometimes updated (not all together but some structure variables as needed). Currently I have created a spiffs partition where I will overwrite a file with all ...

Hi everyone, I’ve added my binary file with that way ( https://docs.platformio.org/en/latest/platforms/espressif32.html#embedding-binary-data ). So my question was to understand if there’s a way to set a priority of position in the “.rodata.embedded” section where automatically files go to with docs...

Thanks for reply! I have another questions: I have a simple .txt files (with some strings) added in CMakesLists.txt like descripted on link in your answer. There's a way to find this strings in the firmware.bin file generated? In the future I will have to modify the firmware.bin file to change the s...

Hello everyone, I need to store the read-only data (100kbyte) in a relative firmware address of the file, to be able to update both firmware and data with a single file.

Someone can help me?

Actually my idea was to erase all at first, and after write. In this way I can mask the erasing time in some way. It seems is erasing sector by sector from https://github.com/espressif/esp-idf/blob/master/components/app_update/esp_ota_ops.c : esp_err_t esp_ota_write(esp_ota_handle_t handle, const vo...

Thank you for the answer. I have another question: If you go into the function esp_ota_write(), there is a cycle that erase and write for each block of data passed in function. If I use esp_partition_erase_range(part, 0, part->size) to erase entire partition, after, for writing the update, there is ...

I'm doing a project where OTA is needed. To reduce the updating time (the update size is about 2.3Mb), I'm searching a way to: - Erasing the next partion in one time, instead of erasing and writing ciclically with esp_ota_write(); - And after update it; It depeands the erasing time of a flash page. ...

Hi I'm searching an example. Did you find something?

Thank you!
