If the update fails, subsequent calls to ESP8266httpUpdate immediately fail until the 8266 is rebooted. Higher and lower values for the max record size also sometimes worked but less often. With compression on the webserver on, updates still succeeded but less often. I think we need a checksum calculated on the update. A few times it thought it succeeded but the update was corrupt. From the other 50% of the time, about 45% of the time it timed out in writeStream on the call to readBytes in updater.cpp.
ESP8266 FIRMWARE UPDATE USING ARDUINO CODE
Update: I did find the code to updateSketch in /cores/esp8266/ I also was able to get the updates to work with TLS about 50% of the time by shutting off compression on the webserver and lowering the max record size to 128. Is this method documented somewhere? I couldn't find the code for it. However ESP.updateSketch(tcp, len, false, false) is returning false. The GET request seems to work well and the server happily sends the update. I hacked up the ESP8266httpUpdate.cpp code for TLS connection.
Socket.error: Se ha forzado la interrupci¾n de una conexi¾n existeįollowing up on the earlier conversation to get ESPhttpUpdate working with TLS, I have a server now restricting its TLS fragment (record) size to 4K. Mean I can upload OTA and it will still be possible to loadĪnother sketch via OTA afterwards, or does every sketch that I upload via Also, what is not clear to me: When I upload OTAtest, does that Work on ESP-01? (If so it would be good to document that fact or put in aĬheck). This means I need a different hardware module, correct? So OTA will not One more thing that you will certainly need in a sketch in order for OTA to Many ESP12/ESP07 modules right now ship with 4M flash.įor now the OTA function is implemented in the sketch, so if you uploadīlink sketch, it won't be able to update. You need at least 1M flash for this to work. This is a very much work-in-progress feature so please forgive the lack ofĭocumentation. You need to have at least 1M flash for the OTA to fit.

Do you flash the ebootīootloader then use the ota_server.py ipaddress any_arduino_sketch Post you had about using the ota_server.py. Make use of it? Was there an example or samples in the wiki? I saw On Sun, Jun 21, 2015, 03:41 prussiap I saw it in the git repo but how do you In a short while this will be integrated into the IDE so you will just have To use OTA you can flash OTATest.ino linked above, and then use
The binary which is generated by IDE contains the bootloader in the firstĤkb sector, so you don't need anything extra - the bootloader will be On 21 June 2015 at 09:01, Ivan Grokhotkov wrote: This is a wonderful project - and it just keeps getting better and better.
