Hi, Thanks for your feedback. So my understanding is if necessary the same binary can be used for 4MB and 8MB but I'll loose the extra space. I'll look further into if a bootloader update is needed when increasing the flash, thanks. Are there are guidelines on adjusting the partition table for the i...

Hi All, I would like to enquire if there are any software changes required when upgrading the flash size of an ESP32 module. In my case, when upgrading from an ESP32-WROOM-32E 4MB to the 8MB type of the same module. I am aware of the SDK config option to set the flash size "CONFIG_ESPTOOLPY_FLASHSIZ...

Hi, I would like some confirmation that the Espressif V3 silicon range is fully compatible with previous silicon versions? Is there a list of how it will affect software and what changes are required? I use the ESP32-WROOM32D and the equivalent is ESP32-WROOM-32E. From what I've found so far, the on...

Just wanted to update with a solution. I came across this thread on the ESP-IDF Github which showed it was a known issue:
https://github.com/espressif/esp-idf/issues/4689

Once I updated my ESP-IDF SDK this was resolved. I updated to v3.3.4 if anyone is curious about a branch that contains the fix.

It's useful to know, thanks.
Can I ask what version of the ESP-IDF you are using?

Hi, I am using an Espressif esp32 wroom-32d running the ESP-IDF in a product that connects to mobile phones over Bluetooth. I am using the Bluedroid stack. Android has a default MTU size when transferring data over Bluetooth. In some cases I need to send large amounts of data so I set the MTU size g...

Hi, I wanted to update this post on the reason for the issue described in my original post. My device previously ran espressif IDF v3.0.x and was being updated to v3.3.x. It was discovered the NVS partition format changed between 3.1.x and v3.2.x. This means when I upgraded from v3.0.3 to v3.3.1 the...

Hi All, I have a device using the esp32 wroom-32d and running esp-idf sdk v3.3.1. When the device reboots occasionally I see the following failed assert: assertion "dataSize == readSize" failed: file "C:/device/user/repository/esp -idf/components/nvs_flash/src/nvs_storage.cpp", line 419, function: e...
