Are you using latest ArduinoBleOTA version? What size of bin file is? Upload by python script or mobile application? if python script, can you show me console logs?
ArduinoBleOTA version - v1 bin file size - 487,696 bytes
*OTA Device Found! Connecting to ArduinoBleOTA HW: Example ESP32, VER: [1, 0, 0], SW: Example SW, VER: [1, 0, 0] Begin upload: attr size: 128, buffer size: 5080 Uploaded: 127/487696 : Uploaded: 487696/487696 Incorrect firmware size
i print in serial monitor 487442 != 487696 (current len != Firmware len)
Thanks
From logs I see that you have outdated version. Please type git pull, will be easier work in same code base.
From bin size I see that default ArduinoBLE
library is used.
Issue happens because of internal buffer to big and ESP32 wasn't able to handle fast incoming packages:
https://github.com/vovagorodok/ArduinoBleOTA/blob/main/doc/ADVANCED.md
I have tested mostly on NimBLE-Arduino
library. Perhaps for ArduinoBLE
library buffer size should be tuned better here:
https://github.com/vovagorodok/ArduinoBleOTA/blob/main/src/BleOtaSizes.h
I have decreased buffer for ArduinoBLE
: https://github.com/vovagorodok/ArduinoBleOTA/commit/a808aead33b4b0a080da2bb6d1e24dbca68a49f6. Please check if it helps
You can run uploader.py second time. ArduinoBleOTA
disables buffer when first upload fails. It should upload successfully but slowly.
You can disable buffer at all by:
build_flags =
-D BLE_OTA_NO_BUFFER
But for NimBLE-Arduino
speed decreases from 12kB/s to 3kB/s.
For ArduinoBLE
from 20kB/s to 3kB/s.
I am trying but can't solve this problem
incorrect firmware size
Connecting to ArduinoBleOTA HW: Example ESP32, VER:[1, 0, 0], SW: Example SW, VER:[1, 0, 0] Begin upload: attr size: 256, buffer size:1020 org.bluez.Error.Failed: Failed to initiate write
attr size: 256 for ArduinoBLE
is to big.That why you can't write to this characteristic.
Fix is on never version of ArduinoBleOTA, please:
git reset --hard
git pull
Add your blinking example main.ino and check if it works
espdev i tried this attr size : 16 buffer size : 512 perfectly flashed.But, very slow. Then i tried this esp32dev_nimble, its perfectly flashed and time also ok.
Thank you for replying.
Upload to existing file esp32 completed successfully. Added the led blinking program to the main file and then some errors in uploading the firmware.bin file to the esp32. Incorrect firmware size error. How to resolve this error
