Hi @KMcLoud - I'm just having a look into this for you! I'll get the docs updated to reflect this as you're right, this isn't very clear!

@michalt38 said in UART handler error: I've got WiPy 1 I can not help more because i have only Wipy2.0. Maybe someone else...

@michalt38 first you must connect to wifi https://docs.pycom.io/pycom_esp32/pycom_esp32/tutorial/includes/wlan.html then you must create socket and send data https://docs.pycom.io/pycom_esp32/library/usocket.html and then use send

@robert-hh Thanks a lot! :)

solved. The problems i had has been level shifter dependend. I used another one and UART started to work. Another trap has been a misunderstanding in PIN numbering and PIN layout. When i just looked at WiPy pinout without paying attention to expansion board i noticed, that i used the wrong PINs. Now i count from left side, starting with 0 and figured out which PINs i do have to use. Now it works like a charm. Thanks for all your help !

No, the callback handler can be inside a class. But then the handler must have self as first additional argument. Example (ESP8266 one, but principle should work) with ISR fucntion sample. class acquire: def __init__(self): self.adc_read = machine.ADC(0).read self.data = array.array("L", [0] * _BUFFERSIZE) self.index_put = 0 def sample(self, x): self.data[self.index_put] = self.adc_read() self.index_put = (self.index_put + 1) % _BUFFERSIZE self.irq_busy = False

@jmarcelino Thx a lot

Hi @michalt38, Maybe you could find the answer right here: https://docs.pycom.io/pycom_esp32/library/ussl.html Mike

@chumelnicu Still on my to-do list I'm afraid, but maybe try iotmaker's code? https://forum.pycom.io/topic/1453/i2c-sensor-with-wipy2/11

seems that is exactly what happened, the description on amazon said the expansion would fit either version, I honestly didnt know I was ordering the old version of the WiPy it didnt have a version number on the description. I rma'd the 1.3 board and ordered a 2.0 board. They should put better description on Amazon for both items to avoid this stuff. https://www.amazon.com/Pycom-C1002-WiPy/dp/B01HFAKK5C/ref=sr_1_1?ie=UTF8&qid=1489281512&sr=8-1&keywords=WiPy

@soren You have to mount the SD card first, before you can see it in ftp. The format I'm using is FAT32. A sample mount sequence is below, taken from the docs. # import os import machine sd = machine.SD() os.mount(sd, '/sd')

@michalt38 to do this you need run Wipy in mode WLAN.STA_AP but for me it can connect to router but i can not connect to it as AP. But i do not tested this in the current firmware - maybe it work now

@michalt38 Here (click me) is a good example about what @livius said.

@daniel I see that some timings/stability improved in pin. Now i am able read samsung tv codes without any problem from python code without need of C function as previously :) I tested this i suppose in many previous versions (last tested lower than 1.5) and it was not stable enought but now it work :)

@mkharibalaji that callback is not yet available, but it's planned to have it implemented.

@daniel I just test this and the behaviour is still as before. Trying to initialize the SD card without a SD inserted raises a OSError exception, which is OK. my English is bad and when i wrote Something was changed. than this was only assumption - i do not test this with current 1.6.3 firmware i tested this on 1.5.0 and it worked - and if for @kanu it does not work then i supposed that he tested this with current firmware Card detection is simply done via a GPIO pin good point - i must connect it :)
