issue with frozen code
Hi,
I followed your instructions for building the frozen code, and I'm getting the following on import:
import uhttpd Traceback (most recent call last): File "
", line 1, in File "uhttpd.py", line 29, in ImportError: no module named 'uasyncio'
I have all the files linked as specified in the modules directory:

Thoughts?
You need to install the asyncio (and other) dependencies.
Please see https://github.com/fadushin/esp8266/tree/master/micropython/uhttpd#frozen-bytecode-recommended
Hi! I also trying to compile firmware with uhttpd and I following this instructions: https://github.com/fadushin/esp8266/tree/master/micropython/uhttpd#frozen-bytecode-recommended But at the moment link https://github.com/micropython/micropython/tree/master/esp8266 is broken and it seems, that directory structure of micropython project is changed. I found directory esp8266 at https://github.com/micropython/micropython/tree/master/ports/esp8266 and I'll check ability of compiling, but documentations needs to be fixed.
UPD: I checked it - I can compile firmware, that contains uhttpd, asyncio, logger. Also I can start server:
import uhttpd
import uhttpd.file_handler
import uhttpd.api_handler
import api
api_handler = uhttpd.api_handler.Handler([
(['system'], api.SystemAPIHandler()),
(['memory'], api.MemoryAPIHandler()),
(['flash'], api.FlashAPIHandler()),
(['network'], api.NetworkAPIHandler())
])
file_handler = uhttpd.file_handler.Handler('/www')
# in documentaion Handler initialized without '/www' parameter,
# but I think it's mistake, anyway, I cat get content from /www only
# if I initialize Handler with path, cause by documentation I uploaded
# content into /www
server = uhttpd.Server([
('/api', api_handler),
('/', file_handler)],
{'max_headers': 50, 'backlog': 10})
server.run()
I append api.py (and then api.mpy - the same situation) into the root. It works if I run it from repl:
MicroPython v1.9.3-240-ga275cb0f on 2018-01-12; ESP module with ESP8266
Type "help()" for more information.
>>> import api
>>> m = api.MemoryAPIHandler()
>>> m.get_memory_stats()
{'mem_alloc': 19648, 'mem_free': 16320}
>>> n = api.NetworkAPIHandler()
>>> n.get_ap_stats()
{'ifconfig': {'ip': '192.168.4.1', 'gateway': '192.168.4.1', 'subnet': '255.255.255.0', 'dns': '208.67.222.222'}, 'status': 'Unknown wlan status: -1', 'config': {'authmode':
'AUTH_WPA_WPA2_PSK', 'hidden': False, 'mac': '0x1afe34d3fc05', 'channel': 1, 'essid': 'MicroPython-d3fc05'}}
But when I trying to get api through web, I got error and repl restarting:
>>> import serv

Wow that's cool. It looks like your ESP (or whatever device you are running on) crashed. Does it crash immediately, or does it crash only when you make an HTTP request to the device?
I'm not sure how to help you here. For me, I usually experience issues like this when I have a faulty power supply.

Couple of hours ago I taked two other esp8266 boards, and flashed them with the same builded firmware. They doesn't crash at all. I can get any api response by curl or browser, so it seems, that my first ESP board is broken. But there are another problem with web-console: I can see console, but in "About" tab I can see only "A web console into your ESP8266" label, "Access Point" label in "Networking" tab and some empty space between labels and footers.
