The SecureTable application has the ability to use Wifi and mobile networks to communicate with your POS system. Switching from one network to the other generally occurs automatically and transparently, but there are situations where users may want to control how and when the application switches networks. One such example is if you have areas at the limit of the Wifi range. In such an area, the terminal may repeatedly switch between Wifi and mobile networks, causing connectivity issues. In this case, the user may want to force the application to use the mobile network all the time while in that area.
Before using mobile networks with SecureTable, the following requirements need to be met:
• Use SecureTable version 4.67.6 or later.
• Use an Android payment terminal equipped with a SIM card. (The SIM card is provided by your preferred mobile network carrier.)
• Configure an APN on your Android terminal to allow Internet connectivity through mobile networks. You can learn how to configure an APN here: Task : Add an APN to Your Payment Terminal.
• Setup Port Forwarding on your router/firewall. A generic walkthrough is provided here: Task : Configure Port Forwarding
• Configure Redundant Network as described here: Configure Redundant Network options
You can always tell which network SecureTable is currently using by looking at the icon in the upper-left corner of the home screen:
SecureTable operating on Wifi SecureTable operating on Mobile
Signal Strength
The icon also informs the user of the signal strength.
Excellent signal Good signal Fair signal Poor signal
No signal
By default, SecureTable will always try to connect to known Wifi networks to reduce fees related to data usage over mobile networks. However, it is possible to force SecureTable to use mobile networks. This is useful to cover blind spots in Wifi coverage or in areas at the limit of Wifi range, where the signal can be unstable.
Touch the Wifi icon in the upper-left corner of the screen.
Touch the LTE signal icon or the SWITCH TO LTE button.
A confirmation dialog will appear. Touch YES to switch to LTE.
IMPORTANT! After manually switching to LTE, SecureTable will not try to switch back to Wifi on its own. If you wish to use Wifi again, you will need to switch to Wifi manually.
Touch the 4G/LTE icon in the upper-left corner of the screen.
Touch the Wifi signal icon or the SWITCH TO WIFI button.
A confirmation dialog will appear. Touch YES to switch to Wifi.
IMPORTANT! In the Select Network screen, the Wifi network appears as if it is unavailable. This is normal. This is because the Wifi antenna of the terminal was disabled during the manual switch to LTE. If the terminal is within Wifi range, switching back to Wifi will reactivate the antenna and reconnect to the network.
When the option Auto-connect to LTE is enabled, SecureTable can attempt to connect to LTE in the event that the connection fails over Wifi. This failover feature will only occur during a transaction process. It will never happen when the SecureTable application is idle.
Start a transaction as you normally would, by touching the ENTER button.
Input your server number and touch OK.
If there is an issue with the Wifi connectivity, the terminal will remain on "Fetching tables" longer than usual.
After a few seconds, an error message will appear: Unable to reach Wi-Fi network, connecting to LTE. Touch YES to connect to LTE.
The transaction process will resume over LTE.
IMPORTANT! After this type automatic switch to LTE, SecureTable will not try to switch back to Wifi on its own. If you wish to use Wifi again, you will need to switch to Wifi manually.
When WiFi signal is lost, SecureTable will automatically switch to Mobile networks, regardless of the status of the Auto-connect to LTE option. This happens without user intervention, as soon as the WiFi signal is lost. When the terminal is brought back within WiFi range, SecureTable will automatically switch back to the WiFi network.
The terminal is brought to the limit of Wifi coverage.
WiFi signal is lost.
SecureTable automatically switches to 4G/LTE mobile network.
