urequest.post gives me an OSError: Network card not available

[Thosch42]

Hi all!
I simply like to post some measurement values to an influxdb.

resp_data = "current,location={0} value={1}".format(location, irms)
resp = urequests.post(db, data=resp_data)
print("response: {}".format(resp.status_code))

I'm using the lates urequests.py from micropython-lib.

The error points me to line 56 of the urequests.py lib

s = usocket.socket(ai[0], ai[1], ai[2])

Someone else getting such an error?

Cheers,
Thomas

Ok...
Digging a bit deeper into the problem.

The request method in urequests.py uses the usocket.getaddrinfo method from the usocket lib to resolve the host ip.
The given ip string is

db = "http://xxx.xxx.xxx.xxx:8086/write?db=energy_db"

and it is splittet correctly.
The result of the usocket.getaddrinfo call

ai = usocket.getaddrinfo(host, port, 0, usocket.SOCK_STREAM)

gives the following list back:

[(2, 1, 0, '', ('xxx.xxx.xxx.xxx', 8086))]

The first list entry is the 'family'. Locking into the docs, FamilyType[2] is socket.AF_SIGFOX.
The L01 doesn't have a SIGFOX modem. So, to try to open a socket with

s = usocket.socket(ai[0], ai[1], ai[2])

leads to the OSError: Network card not available.

I'm using Pycom 1.20.0.rc13 [v1.9.4-94bb382] firmware. Is it probably a bug?

Cheers,

urequests.request("POST","http://IPADDRESS/api/v1/TOKEN/telemetry","{\"temperature\": 25.01,\"pressure\": 1.02}", None, {"Content-Type": "application/json"},None).text

This worked for me to post to thingsboard

after changing

ai = usocket.getaddrinfo(host, port, 0, usocket.SOCK_STREAM)

to

ai = usocket.getaddrinfo(host, port)

But when I got an error I had to power off to make it work again.

urequests.py

release='1.18.2.r7'
