if you send the files line by line, did you add a delay after each line? If at the XBEE side uart.readline() is used, it requires some time to process the data.

I just rebuilt that code, with exactly the same table, for a 8 MB device # Name, Type, SubType, Offset, Size, Flags # Note: if you change the phy_init or app partition offset, make sure to change the offset in Kconfig.projbuild nvs, data, nvs, 0x9000, 0x6000, phy_init, data, phy, 0xf000, 0x1000, fac...

I recall having successfully made the changes to the partition map. I' ll look into it and tell later.

So you want to send two python scripts to the XBEE. And you want top send them from a STM32 micro. May I ask you why you do not use a PC to send the file over USB to the XBEE? That is the most simple version, either using the XCTU tool or pyboard.py. With respect to the messed up indentation: did yo...

File accesses are buffered. So even if the stream is read byte-by-byte, there is a buffer in the way. But caching may get a problem, if the code and memory areas touch in the way are larger than the cache size. As far as I recall, a cache refresh takes 100-300µs. If that happens for every byte of th...

Does pyboard.py work with the XBee?

Yes

_thread.exit() will be called from within the newly started thread.

I didn't note some radical differences with the previous script.

The difference is when you push a function or cursor key, which issues two bytes. These are then displayed in a single line. Indeed not a huge difference.

No, I do not know any better single code. You may eventually use a control code which is more rarely used, like Ctrl-T (in pye: go to line 1). Or you go for a function key. For that, you have to move the exit call into the branch after while ch in b"\x00\xe0": # arrow or function key prefix? I modif...

How do you stop the code running once it's started with start_new_thread?

Call _thread.exit()

Am I right to assume that you cannot pass a single parameter to a function with start_new_thread? I get a tuple error when I try sending just one.

You can pass a single element tuple: (value, )
