For several days I create a project in which I have a Linkit One connected to WiFi, functioning as a WebService client sending the following information using GET:
GPS: Latitude and Longitude
Analog sensor value of 1
Value of 3 Switches
The information is sent every minute.
Initially I thought it would be problem because RAM used various STRING variables, thus optimizing the variables and also use the Flash to send texts and not saturate the RAM.
However at this time after several hours (24-30), The linkitOne disconnect from WiFi, stops sending the information and the TX and RX LEDs begin to flash continuously and slightly.
From there just restarting the button, the LinkitOne starts sending information.
That can happen?
I share the code for some help
