False alarm. The memory use is from this line:
Comment that out and some commands cause a drop in free memory as they set up stuff (or call stuff) but that then remains static through further commands. More importantly, my code now works as expected, which is a plus

I am trying to implement some console commands and have a bunch working that don't use command line parameters. That is, they are simple single-word commands. However, if I introduce arguments to a command I get a 24-byte memory leak whenever it's run. Looking at the argtable tutorial , I see they c...

I'll see what I can do.

If anyone is still interested in this, I think I found the cause... It is rmt! Yes, nothing to do with radio at all. Just a coincidence that my project uses rmt to drive a bunch of LEDs which come on a little before the radio is connected. It takes a couple of seconds for rmt to overwrite memory, he...

Kind of fixed by setting the SPI flash implementation to 'legacy'. Not a proper fix since there are still errors on the mux link, but they are recoverable. I think the problem with non-legacy SPI is just that the errors are more numerous and bigger, so not recoverable and hence the data loss. Still ...

Got exactly the same problem here with this. Talking to a GE310 via lwip PPPoS and the Telit cmux protocol, file downloads perfectly even with two other serial streams coexiting over the mux. Enable esp_ota_xxx() functions and the serial packets get corrupted. It seems to me like a flow control issu...

Yep, did the update, mostly because I wanted to be sure the updated nimble module was there, and it was easier to update the lot than just that

I have a project using an Wroom-32 which I developed using ESP-IDF 4.1 and the legacy build tools (i.e. msys2). But 4.1 is behind the times so I tried moving up to 4.2 (legacy tools with 4.2 Dev and Cmake with 4.2 relaese). With any 4.2 version the Wroom resets as soon as I enable Bluetooth: I (1318...
