@Gijs Yes! Tested rc11 yesterday and it worked just fine. Thx!

@troy-salt If you have access to the device, you can read the flash with esptool.py.

@paul-thornton no it was something else. i don't remember what the exact problem was. one thing that is weird is that the WLAN SSID was never changed. i connected it to pybytes via the REPL and updated the main.py in there and i could connect again.

@kjm But maybe since we are mentioning it... someone who already has a fix can pass it along. Or someone who didn't realize it was a problem can make the next version a little bit better. Hopefully shared misery will have a shared cure. ;)

I am using a W01 module connected via P0, P1 (the standard Rx/Tx lines of the serial REPL) to a FT232R serial-USB-interface. The FT232R is powered from USB. By defining P0 (i.e. Rx) as input with pull down activated, it is possible to dectect if REPL (i.e. the USB) is connected (P0=1=yes) It may be interesting to note that UART operation is not affected by having Rx(P0) declared as digital input simultaneously. By this method, the module detects a serial console during boot and continues in REPL mode. If there is no active serial connection detected, it autostarts its application. I am not sure if this works with a Wipy since the serial-USB interface may be powered from the Wipy, possibly making the status of Rx independent of the USB cable connection.

@robert-hh Thanks, that did it! I had to do the P12 to 3.3V for the 7-9s to load the factory firmware. I retested a firmware update and it went back to the unresponsive mode. So I then reformatted the /flash area by running: import os os.mkfs('/flash') A firmware update then worked ok. Thanks again.

@robert-hh yeah the P12 reset worked out. Thank you :)

Hello, Thanks for reporting this issue. We will investigate it. Cheers, Daniel

@sandipg The voltage and capacity are OK but it's the wrong connector, you want a JST PH-2 (also check the polarity as there is no standard) For Germany perhaps check out these two from HobbyKing: (the higher capacity 2000mAh is cheaper as it's on sale, but see dimensions etc) https://hobbyking.com/de_de/turnigy-2000mah-1s-1c-lipoly-w-2-pin-jst-ph-connector.html https://hobbyking.com/de_de/turnigy-1200mah-1s-1c-lipoly-w-2-pin-jst-ph-connector.html

@robert-hh @crumble Thanks - problem solved.

@jcaron It worked! My bad. Didn't even think about that. I erased flash memory and uploaded most recent firmware. Thank you @robert-hh as well. For the future, are there any best practices for connecting/disconnecting, from both a hardware and software standpoint. e.g. my boot.py file: import os from machine import UART uart = UART(0, 115200) os.dupterm(uart) Should I include anything else?

@ccarducci you could enable a for loop running every second, this way you can interrupt your program every second.

@mhellar That is a common problem with 1.10.b1. Erase flash and reinstall.

@livius thanks again Bookmarked ... Stephane A.

@gouao Have you deleted the first line? The first line cannot be deleted. # main.py -- put your code here!

@peter Thanks a lot for your detailed bug report. We will try to reproduce it, and fix it for the next release.
