@livius @jcaron <SOLVED> I managed to get this to work thanks to your help, used a sparkfun MAX3232 to step down the RS232 to UART and ASCII strings appear as expected and was able to upload them to a web server.

@seb Yup, that solved it

@seb Same reaction here... I think however there are cases when Ctrl-C will not interrupt the currently running code right away, but have an effect only once the current call is finished or something, maybe that's related? We don't quite know what code was running... Or maybe... @pierrot10, had you actually deleted the console in Atom (clicked on the bottom part of the window) before hitting Ctrl-C?

Any News?

@seb Is it possible to use this method with encrypted flash? I mean, is application capable of writing/modifying the json file if the flash is encrypted? And if so, does these changes count for those 3 FW flashs overs USB?

Hello everybody, I have tested the Lopy with the gc.collect function. It isn`t giving a error message anymore! Thanks for the help.

@jojo The problem is that I have insufficient knowledge in python. I cannot write a working script that(for example) reads a DHT22 sensor and formats the data in LPP. Thats why I want a working example with a real sensor.

Class B is currently not supported in the pycom firmware for the Lopy. You might be able to write some addition to the firmware to build it yourself, though I suspect it will be some work

Hi @gruia-nichita I'm using LoPy with Blynk via WiFi, but am also interested in using it with LoRa, let me know if you find a solution (I haven't looked at LoRa+Blynk with enough detail yet...) I'm using BlynkLib : https://github.com/vshymanskyy/blynk-library-python

@pierrot10 Yes, you can use a FTDI cable, or a RasPi. YOu need to connect Tx, Rx and GND. Verify that the output voltage of the adaper is set to 3.3V, since ESP32 input are not 5V tolerant.

@robert-hh Sorry, I misunderstood. I didn't take the pin's voltage with the 1V connected, however I took the voltages of other pins without anything connected. I think the input-only pins were fine, as was pin 20 (and a few others) but some GPIO pins were outputting between 1-3 volts.

@seb It's my bad. I have missed that service was listening just on localhost, that's why I was not able to receive any file.

@testos As long as you do not use SPI this does not matter. And the SPI pins can be reassigned too. And P11 (External IO 8) seems not to be connected on pytrack. Using I diode tester, I cannot detect any connection. At P10 (external IO 7) seems to be used. At least is show something like a ESD diode behavior of an active chip pin.

@wstallwood As far as I know you can’t do it directly from micropython, but you could easily build a custom image from source adding a few logs where appropriate.

@fred said in When is the Deep Sleep Shield required?: Ultra Low Power mode is available on the devices straight out of the box. It's probably also worth mentioning that it doesn't work...
