Arduino esp8266 some times data will not be sent to thingspeak.com I have made an arduino IOT that sends temperature data to thingspeak and works fine . Now I have two questions
1-  In spite of active wifi connection from esp8266 toward the web , but why sometimes that is random the sensor data will not be sent to thingspeak.com ?
2- I need an android app that monitors the wifi and shows the sensor data that is collected by arduino and sent via wifi by esp8266 toward android hot spot , is any app available for this purpose?
Thanks a lot
َAbout first question I found after AT command AT+CWJAP=&quot;network&quot;,&quot;password&quot; it takes a while to have  active and ready wifi connection  , so I used a 30 seconds delay after this command and then send sensor data toward thingspeak.com ,  now  problem is solved .
