I apologize - that first message/topic was lousy.
I have a ESP8266 Python script (below) that uses the urequests module to successfully put to a property on the academic ThingWorx.
This same ESP8266 Python script, with appropriate changes in URL and appKey, generates an ssl handshake status of -40 when trying to put to a property on an evaluation server.
Anyone have any ideas as to why?
---script follows--
import micropython
import network
import urequests
import ujson
yourWifiSSID = "SSID"
yourWifiPassword = "password"
sta_if = network.WLAN(network.STA_IF)
sta_if.active(True)
sta_if.connect(yourWifiSSID, yourWifiPassword)
while not sta_if.isconnected():
print(".", end="")
pass
print()
print("connected to network")
url = 'https://academic.cloud.thingworx.com/Thingworx/Things/OfficeWX_userName/Properties/LightLevel'
headers = {'Content-Type': 'application/json', 'appKey': 'xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx'}
payload = {'LightLevel': '500'}
putreq = urequests.put(url, data=ujson.dumps(payload), headers=headers)
print("Mission Accomplished")
