Script to set the URL for a HTTP request
|
|
Ex:
|
|
/usr/bin/python3 /var/www/nebuleair_pro_4g/SARA/sara_setURL_uSpot_noSSL.py ttyAMA2 api-prod.uspot.probesys.net
|
|
To do: need to add profile id as parameter
|
|
|
|
First profile id:
|
|
AT+UHTTP=0,1,"data.nebuleair.fr"
|
|
Second profile id:
|
|
AT+UHTTP=1,1,"api-prod.uspot.probesys.net"
