will do,
regarding the esp32:
hard reset (power down) program starts just fine but
when the program exits .. closing a UDP socket and closing the wifi connection
it sometimes will never connect to wifi again.
^D in repl to start will sometimes not connect to wifi....

This sounds very similar to the problem that was mentioned at https://github.com/micropython/micropython/issues/4269. It was fixed for v1.10.

Hello Damien,
regarding the latest version: v10.10-98
the esp32 looks really good, but i am having a problem with the 8266 (not version specific)
in Station Mode all is well sending continuous 8 bytes through a socket with UDP protokol every ~14ms.
but when running in an Access Point mode there are frequent drop outs and reconections.
it takes on average 250ms to recover.
on the ESP32 with the same program same sensor same timing no dropouts.
below you see the data from the serial console:
the first 3 numbers and their sum is sent to the socket.
the number after the ^ is the time interval in us.
my question if you have the time:
does the 8266 have a stability issue as an AccessPoint (server) that you know of?
the data rate is low about 4.5 kBits but the realtime spacing needs to be preserved.
thank you for your time...
so long

v1.10: Vast improvements to native emitter, new nrf port, unified documentation

http://docs.micropython.org/en/latest/e ... e-firmware

Seems impossible to update documentation - still lists erase as a separate command.

No, not impossible! This was on my list for the next batch of documentation updates but it didn't seem that important. In fact I probably prefer the two separate commands since the one-liner hasn't made it to the esptool readme yet...

Happy to hear this news and am very pleased to have found it.Thank you to all who worked in this. Good job guys.
