Systematic lost of Certificate after OTA SPIFFS upload #158

Closed FredericGuerne closed 4 years ago

FredericGuerne commented 4 years ago

Hello,

Systematically I recieve the following message : "Could not load Certificate!" at next call home, for app. and SPIFFS OTA update, after a previous successful SPIFFS update.

I have to go back in config. mode to ask for a new certificate to make it working again it looks like SPIFFS file overwrite the certificate data ?

My configuration : IotAppstory-ESP 2.1.0 RC3 ESP32 PlatformIO Visual Studio Code

Best regards

Frederic

Could u share how much memory u allocated to spiffs?

FredericGuerne commented 4 years ago

My spiffs.bin is 1472 Kb, but I am not sure it is the allocated memory you talk about, sorry ?

CwlBroeders commented 4 years ago

I was referring to the amount of flash memory set to be allocated to spiffs in your IDE settings, but i dont think thats the problem

Have u added the certificate to the files that get compiled to spiffs.bin?

In the data folder u should make a folder named cert, this folder should contain the certificate, u can download it here. https://iotappstory.com/ota/iasRootCa.cer

(its a recent change in workflow so we have not yet added it to the documentation properly)

The IAS wiki has been updated to reflect changes.

Hi @CwlBroeders and @FredericGuerne ,

I can confirm that this instruction does in fact work. I also confirmed that omitting the /cert/iasRootCA.cer from the SPIFFS will in fact cause the certificate that was there when configuring the device to be lost and thus it won't successfully call home anymore until the certificate is added again from config mode. Adding the certificate in the SPIFFS does in fact fix the "lost certificate" problem.

Thanks for this question (I happen to have just started thinking about adding some SPIFFS functionality to my sketch and @FredericGuerne 's question and @CwlBroeders answer came exactly at the right moment).

PS: using Platform IO with Atom as editor, IotAppstory-ESP 2.1.0 RC3 and and MH-ET Mini Live ESP32 in case that is relevant.
