I have to admit that I had some bad experience when trying to flash new firmwares to my ESP-01 modules but today I have found an easy and reliable way to flash ESP8266 firmware v1.5 (AT v0.51) using my Arduino Uno board as an FTDI controller.

Mac OSX and iOS - support is already built in / no any extra You can use another module if it meets previously described requirements.īefore you begin, please make sure that you have the followingĪrduino IDE and 2.0.0-rc1 (of Nov 17, 2015) version of platform The sample implementation provided below has been done using:Įxample sketch WebUpdater.ino available in Alternatively, if someone else copies the private key, then they will be able to use it to sign binaries which will be accepted by the ESP. Loss of the private key associated with a binary means that you will not be able to OTA-update any of your devices in the field. The same private/public key pair that was used with the original upload must also be used to sign later binaries. Signing also does not encrypt anything but the hash (so that it can’t be modified), so this does not protect code inside the device: if a user has physical access they can read out your program. If someone has physical access, they will always be able to flash the device over the serial port. If the code is modified or replaced in any way by anyone except the holder of the developer’s private key, the signature will not match and the ESP8266 will reject the upload.Ĭryptographic signing only protects against tampering with binaries delivered via OTA. The signing process computes a hash of the binary code, encrypts the hash with the developer’s private key, and appends this encrypted hash (also called a signature) to the binary that is uploaded (via OTA, web, or HTTP server). Signed updates are updates whose compiled binaries are signed with a private key (held by the developer) and verified with a public key (stored in the application and available for all to see). This uses SHA256 hashing in place of MD5 (which is known to be cryptographically broken) and RSA-2048 bit level public-key encryption to guarantee that only the holder of a cryptographic private key can produce signed updates accepted by the OTA update mechanisms. For applications where a higher level of security is needed, cryptographically signed OTA updates can be required. While the above password-based security will dissuade casual hacking attempts, it is not highly secure. Chapters below provide additional information regarding security and safety of OTA updates. The developer should ensure that the application running on the module is shut down and restarted in a safe manner. Once the update is complete, the module restarts, and the new code is executed. It is up to the developer to ensure that updates are allowed only from legitimate / trusted sources. If the OTA routines are correctly implemented in the sketch, then all subsequent uploads may be done over the air.īy default, there is no imposed security for the OTA process. In any case, the first firmware upload has to be done over a serial port. The other two options would be more useful after deployment, to provide the module with application updates either manually with a web browser, or automatically using an HTTP server.

The Arduino IDE option is intended primarily for the software development phase. Such functionality becomes extremely useful in case of limited or no physical access to the module. OTA (Over the Air) update is the process of uploading firmware to an ESP module using a Wi-Fi connection rather than a serial port.
