When download a .dwl file from M2MStudio 1.1.1, my download finishes when it reaches 280/279 blocks!! :open_mouth:

Yeah, happens very often and 100% when working with Q24, it reaches over 100%, then gives an error, but the file is actually loaded fine. Adds to the fun in programming :smiling_imp:

I’ve not seen any errors - just noticed that it seems to count 1 more block than “required”!

yeah, regularly uploads more bytes when the reported size, no error is given, and is seems to be consistently at 1-2% overrun.

Is it actually sending extra bytes on the wire, or is it just mis-reporting it?

Dont know why, maybe because of no hardware flow control (Q24 with half-duplex RS-485), but i never especially succeed software download with m2m studio. Or even recommended Xmodem-1K at all. Too slow, periodic freezing, sometimes abort with strange error messages… The best and fastest solution i f…

Wavecom’s 1K-XMODEM implementation for the software download certainly does require hardware flow control: forum.sierrawireless.com/viewtop … ow+control See my post right at the end of this thread: [ forum.sierrawireless.com/t/download-the-dwl-application-with-only-rx-and-tx-ua/251/13 ) It seems t…

awneil, do me a favor, i’m curious: how fast Xmodem-1K with hardware flow on large project? For comparison.

It’s just a known issue about progress reporting (planned to be fixed in TM refactoring, the same for the pause every 50-60 blocks…). Don’t worry, no extra bytes are sent.

E?? I thought that was actually due to the module - as this is the same irrespective of what XMODEM implementation you use (Hypoterminal, custom implementation, etc) :question:

It is actually mainly a specific Studio issue. The pause typically occurs when the protocol falls in timeout while a flash memory sector is erased. Maybe it can occur from times to times with other tools like HyperTerminal, but clearly less often than with the Studio.
