Can't write properly on SD
Hey guys! so that's my code....
if not lora.has_joined(): try: if sd != None: print("SAVED!!!") pycom.rgbled(0xfd6a02) time.sleep(2) with open('/sd/' + LOG_FILENAME, 'a') as f: f.write("banana") #f.write(bytes2send) print("Printei isto!") print("Passei aqui!") except Exception as e: print(str(e))
the problem is... if i write only the string, the string is written no flaws!
but when i try to write the bytearray and the string, he doesn't write the string no more and only numbers appear
can someone explain this?
Thank you in advance!

@morrison You should convert that to a printable version before writing, e.g. either with ubinascii.bin2hex(bytes2send)) or as repr(bytes2send)
I'm opening the SD card via usb bytes2send is a byte array with values for example
bytes2send = bytearray(b'\x00@\xb3\xbd\x00 O>\x00\xa0v?\xef\xf6<\xc1W~\x98@x\x01\xb5\x0b\x00\x00\x07C\x00\x00\xfeB\xee\x03/')
@morrison What are the contents of
bytes2send? How do you check/view your log file? You may want use
hexdumpor an equivalent tool to see what are the actual contents of the file. If you just
catthe file and it contains a
CRfor instance, you might not see everything...
