MicroPython • Re: How to receive large (>1024 byte) UDP datagram packets?

When I look at the number of packets it received before stalling, it's always 24.

Good spot.

My 'fails after 1022' was after sending a 40 packet byte then increasing from 1000 - 24 in total.

A test from 100 upwards fails after 123 bytes - again 24 in total.

A test of 1400 up stops at 1423 - again 24.

But, a test of 2000 up - stops after 12

A test of 4000 up - stops at 8

For 8K packets - stops after just 4

So it's looking like some kind of memory exhaustion issue to me. The question would be where; in the CYW43, its driver, in LwIP or elsewhere ?
