Hi, I’ve found the problem: power source. I’m using esp8266 only with resistor and cap and with an external usbtoserial converter, no nodemcu or huzzah board. When I power device with a strong power source and not from vcc of usb, wake normally, and it’s no problem, I can see the serial message anyw...

Ho, I have a led to a gpio that turn on for ten seconds in the main.py file after boot file, after this time start a script with the sleep function, so if the awake do a reset, I believe I can see the led on after wake, but it turn on only if I do a manual reset. I’m using an esp8266 with a usb to s...

I disconnect gpio16 when I flash and reconnect after flashing.
when I use this script the device go to sleep but wake up only with manual reset

Hi, this one from the documentation: import machine # configure RTC.ALARM0 to be able to wake the device rtc = machine.RTC() rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP) # check if the device woke from a deep sleep if machine.reset_cause() == machine.DEEPSLEEP_RESET: print('woke from a deep s...

Hi, I have an esp8266 running micropython v1.9.3 , I'm trying to work with the deep sleep and it work, but also if I have a connection between reset and GPIO16, using the script like the example in the documentation, the chip go in sleep mode but I can wake it only with a reset to gnd. Seems alarm0 ...

Hi, could someone, if possible, let me understand how micropython orders the probes when there are more than one? with the scan() I can see the address of the probes and I can print the single probe read with a sort of list, but if I reboot the esp8266 or if I change one probe, for example the probe...

hi,
is there anyone who knows exactly how many credentials are saved in the flash and where?
if only the last configuration is taken into account, why are so many saved?
is there a way to 'read' the others too? thanks for the answers and sorry for too many question!!

What I see is an absolute limit on the length, if I add character is always truncated at 52 of body . The entire response of 536 includes all the header, token from Postman, body, etc. I notice that in the 'socket.recv(bufsize)' I can decide the size of buffer to receive, but not more than 4096? 409...

Hi, I solved checking the len of the response and printing only the part after '\r\n\r\n' , the body of a POST. Now my queston is: what is the maximum length possible to receive? Now I have '.recv(4096)' and the len of the entire response is 536, the len of the body is 52. All outside of 52 characte...

Hi , i'm trying to use a web server example from micropython on esp8266, but I don't understand how to read the body of a POST request . I send the request from Postman and I receive all the header. I've try to check if Content-Length is present to print the query. I receive the correct length of th...
