3 years ago Test code is a simplified Requests simpletest:
import board
import busio
from digitalio import DigitalInOut
import adafruit_esp32spi.adafruit_esp32spi_socket as socket
from adafruit_esp32spi import adafruit_esp32spi
import adafruit_requests as requests

# Airlift FeatherWing:
esp32_cs = DigitalInOut(board.D13) # Red LED
esp32_ready = DigitalInOut(board.D11)
esp32_reset = DigitalInOut(board.D12)
spi = busio.SPI(board.SCK, board.MOSI, board.MISO)
esp = adafruit_esp32spi.ESP_SPIcontrol(spi, esp32_cs, esp32_ready, esp32_reset)
print("Connecting to AP...")
esp.connect_AP(secrets["ssid"], secrets["password"])
print("Connected to", str(esp.ssid, "utf-8"), "\tRSSI:", esp.rssi)
# Initialize a requests object with a socket and esp32spi interface
socket.set_interface(esp)
requests.set_socket(socket, esp)
# out to lunch (line 122) or ValueError: invalid syntax for integer with base 16 (line 220)
TEXT_URL = "https://anecdata.dev/ada/chunked2/?oc=7&ic=3&tr=17&ot=0&it=0"
print("Fetching text from %s" % TEXT_URL)
response = requests.get(TEXT_URL)
print("-" * 40)
print("Text Response: ", response.text)
print("-" * 40)
response.close()
This one only manifests on Feather RP2040. It doesn't happen on PyPortal or FeatherS2. Some primitive behaves different? A timing quirk? Flash issue? Other??
This URL comes back as a chunked response, but loads fine: https://anecdata.dev/ada/chunked2/?oc=8&ic=4&tr=28&ot=0&it=0
But this one hangs up on receiving: https://anecdata.dev/ada/chunked2/?oc=7&ic=3&tr=17&ot=0&it=0
The parameters affect the data size. My only intuition is that round numbers seem to be fine, but less-round (odd?) numbers fail. The failures manifest as hanging on receive in line 122 of Requests:
(^c after a minute of waiting)
or in reading the chunks, as in:
In my 'prodution' code, it's always the latter situation. I haven't been able to run Feather RP2040 + Airlift from the beginning.
I doubt it's an Apache issue since it returns fine in the browser and with
curl --http1.1. Old Requests was HTTP/1.0, chunked responses are a fact of life with HTTP/1.1.I've tried this on various versions since the board became available, most recently with
Adafruit CircuitPython 6.2.0-beta.4 on 2021-03-18; Adafruit Feather RP2040 with rp2040andAdafruit CircuitPython 6.2.0-beta.3-142-ga5c675932 on 2021-03-12; Adafruit Feather RP2040 with rp2040(the slower flash version from https://github.com/adafruit/circuitpython/pull/4392 )I've spend a lot of time print-debugging this and I'm baffled. By the way, this Feather (I only have one) still has the disappearing-on-reset issue, even with the slower flash version UF2. But large file copies that were a problem before are no longer a problem in the slower flash version or in beta.4. So this could be some weird flash issue, though I've seen no other issues since the slower flash commit.
