PING fails on ESP8266 #21

Closed jerryneedell closed 5 years ago

jerryneedell commented 5 years ago

the espatcontrol_simpletest.py fails on an esp8266. The ping code in adafruit_espatcontrol.py looks for the response "+PING:xx" where xx is the ping time. This is correct for the ESP32, but the ESP8266 only response with "+xx" - the "PING" is not there so the code rejects the response

ESP8266 example -- you can see the responses but no "PING"
