I have an arduino uno 3 connected to my esp8266-esp01. I have a sketch on my arduino that read water level and then sends it to thingSpeak

using software serial with AT commands. I wanted to be able to put in new ip and password so I connected up and put wifimanager on the esp8266 and everything worked out fine. I connected and put in new ip and password, esp8266 rebooted and connected to wifi. The problem is now how do I send sensor info to thingspeak since AT commands don’t seem to work anymore. Get error "’espData" was not declared in this scope. HELP
