The control board communicates with the Wi-Fi radio separate from the Local Area
Network (LAN) and Internet. The radio and control board passes operational data
back and forth to ensure a seamless connection between them. The first step in
diagnosing a communication issue is to ensure the radio and fryer are communicating
together. Various states are as follows:
• Idling: This state indicates the fryer software is initializing its software stack and delaying
before contacting the radio. The fryer adds in a short time delay to allow the radio module
time to initialize itself before communication is attempted.
• Connecting: This state indicates the fryer software is starting to communicate with the radio
module. This state checks that there is a radio module attached and tells the module a fryer
control is attached in order to begin full communications.
• Negotiating: This state indicates the fryer software has successfully communicated to a
radio module and next begins determining security properties of the communications link.
This includes first authenticating to each other to help prevent unauthorized modules from
being attached. It also determines method of encryption of subsequent data, if any.
• Waiting for Fryer: This state indicates the fryer software is doing very early initialization of
the basic communications stack. You should never see this state because this is normally
done very early on in the boot process.
• Waiting for Radio: This state indicates the fryer software has opened a successful
communications connection to the radio module, but the radio software needs time to fully
complete the connection. During this time, the radio module is attempting to establish a
connection to the Internet. It also has built-in time delays to allow the fryer to boot and
initialize. Depending on the sequence of events, this state may be very short or may be up to
several minutes long.
• Connected: This state indicates the fryer and radio module are successfully communicating
to each other. This is the desired state for actively being able to send and receive data
during normal operations.
• Ending: This state indicates the fryer software or radio module has asked to terminate the
data communications link. This usually occurs if the radio module has received an update for
itself and needs to reboot to complete the update.
