Nice, what is the battery life using lipoly and what is the battery capacity.

I am also trying to decide on high capacity AA cels, or lipo / liion foi my project which will be deployed on the other side of the world !

How do you calibrate the RTC ??

I am using the esp.deepsleep() function, works fine until I try and sleep for 1 hour or more.

This results in numeric overflow, what is the maximum sleep time that can be set using this method ??

To save me re-inventing the wheel, does anyone have a code snippet that I can use to connect to a socket server and read a file line by line and save it locally ?? I am trying to create a self update app ?! Or would it be better for the server to serve a file line by line as requested by the client,...

I am using the check_msg() to retrieve any waiting messages, and it crashes whenever it receives one. I suspect that the cause is the QOS which is set on the incoming message and the umqtt_simple library is not handling it ?? checking... Traceback (most recent call last): File "<stdin>", line 1, in ...

Ahh, sorrie, I missed that at the beginning of the post.

So 2973 = 3277.4 mv

i.e. ADC(0).read() * 1.024

Does anyone have a faster, more concise, low RAM WLAN connection routine that falls back to AP mode if it can't connect to the wlan ? def connect(timeout=10,ssid=None,passkey=None): from network import WLAN,STA_IF, AP_IF sta = WLAN(STA_IF) if not sta.isconnected(): sta.active(True) sta.connect(ssid,...

Thanks, but the reading I am getting looks like a millivolt value and not a 0 - 1023 value ! >>> import machine >>> vcc = machine.ADC(1) >>> vcc.read() 2973 Update I have verified that if I change the supply voltage, this reading also changes, however comparing the VCC pin with a voltmeter provides ...

Thanks, but that just results in 65535

>>> from machine import ADC
>>> ADC(0).read()
65535
>>>

This link address specifically mentions reading channel #1 of the ADC ?

The Board is ESP-12S. Is the method shown here the recommended method of setting the registers to allow reading the A/D value of the VCC pin, or has this now been integrated into the firmware ?? https://github.com/micropython/micropython/issues/2352 import esp from flashbdev import bdev import machi...

Hi; I know that I am not really answering your question, but I always use 1024 bytes in the receiving buffer: while True: conn, addr = self.sock.accept() raw = conn.recv(1024).decode('UTF-8') if not raw: print('Null Request.',addr) self.close(conn) else: self.request(conn,raw)
