Hi,
I tried to import an excellent custom SIP - VOIP module. https://github.com/astoeckel/femtosip
(This great SIP protocol implementation allows ringing voip line. I need this for to make a remote belldoor ring with ESP8266.)
In spite of its name implies "femto" (very small) - it seems still too big for ESP8266.
Unfortunately i have this error message:
Code: Select all
>>> import femtosip
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
MemoryError:
>>>
My ESP01 has 1Mbyte only.
Then i tried with Wemos D1. ESP12 4MB Flash - but same error message.
As i understand ESP01 and ESP12 RAM size is the same...
>>> micropython.mem_info(1)

Then i tried to compile this module to .mpy as i read it will provide frozen code.
Code: Select all
./micropython-master/mpy-cross/mpy-cross -mcache-lookup-bc femtosip.py
Code: Select all
>>> import femtosip
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: incompatible .mpy file
>>>
but im not good enought python programmer to do.
Or any advise to resolve mpy compatibility issue?
best regards,
Robert.
