OTA DFU speed

[Sergy]

Hi,

We are using OTA update in production and currently it takes about 40 seconds to update 70KB image. Is there a way to improve the speed?

Thanks!

indeed im using mcp 3.10, but i dont use application itself, just doing it from command line with python script.

Is it possible that it's not invoking the correct dfu_transport_ble.py script? Sounds like the change you did is not being applied.

Can you share the command line arguments so I can try the same here?

its using the right script, because if i make a mistake on purpose and break the script it doesnt work:)

here is my command line:

"c:\Program Files (x86)\IronPython 2.7\ipy.exe" main.py --file c:\Keil_v5\OTA_NOBL.zip --address f1b472ce7137

Im wondering if the screen printout slows down the progress may be?

I'm unable to reproduce your setup here. Please try to do this via MCP. You can always re-install MCP if you break the script, or better, just do a backup of the scripts that you do modify.
