AttributeError: 'bytes' object has no attribute 'decode' #74

Closed jeremyfsu closed 2 years ago

jeremyfsu commented 2 years ago

I'm using CircuitPython version 7.0.0 on the Feather M0 Lora board. Also using a Beitian BN-220 GPS. Getting this error when trying to parse GPS: main.py output: ('GPGSV', '3,3,11,21,28,129,21,27,31,045,15,30,40,311,33') Traceback (most recent call last): File "main.py", line 53, in File "adafruit_gps.py", line 282, in update File "adafruit_gps.py", line 588, in _parse_gsv AttributeError: 'bytes' object has no attribute 'decode'

I'd be grateful for some help, Thanks! Jeremy

It appears that this incompatibility with low-spec boards was probably introduced together with addition of GSV GSA sentence parsing:

@lesamouraipourpre not all circuitpython microcontrollers have bytes.decode. A possible alternative, assuming the message is ASCII, is "".join(chr(c) for c in talker)

jepler commented 2 years ago

str(talker, 'ascii') is more natural than the first alternative I suggested, and is already used.

@caternuson sounds like this is fixed?

caternuson commented 2 years ago

@tekktrik Yep, should be.

@jeremyfsu Please try updating to the 3.9.8 release of the library: https://github.com/adafruit/Adafruit_CircuitPython_GPS/releases/tag/3.9.8 which should be available in the library bundle: https://circuitpython.org/libraries

Closing since it seems like the issue was resolved!
