OTA using SIM800

[thbl]

Hi Guys
Does any one have an example on how to do a OTA over sim800 and arduino ?
-Or how/where can i get startet with it ? :)

I have successfully made OTA for ESP8266. In general:

1. Send a request to the server.
2. Read raw response to some kind of memory using read method

uint8_t file_buffer[512];

 while (client->available()){
int read = client->read(file_buffer, sizeof(file_buffer) - 1);
//save file_buffer somewhere
}

3. Update.

So, you need to find out if it's possible to make OTA for arduino and how it works. There is no problems downloading a file using TinyGSM.

@hubaksis after downloading the bin file where did you save the file and how do you upload the file from there. I am really a rookie to this, trying OTA for esp8266 using SIM800. can you share some details how its done, please

[hubaksis]

File is saved to the SPIFFS (docs here)
Then you need to perform an update from SPIFFS.
Update: example is here

Thanks @hubaksis !

Hi guys, I have a problem.

I use esp32 and a sim800l modem.
I need to do OTA update safely, so there is no risk of a device breaking with a failed update.
However, apparently the tinygsm communication object is not supported for the standard OTA update function.
I have a large program, almost 1mb of code.
I looked at people downloading the BIN file for SPIFFS and then updating. Is this 100% safe? Is there a risk of failure and killing equipment that is remote?
I tried to implement it but I couldn't because the . BIN is too big.

Maybe if I change the file system to 1M of program and 3M of SPIFFS. It is possible?

If there is another way, can you help me?

Thank you

And update on this? (Pun not intended).
