For smooth Mobile Waiter operations, high-quality wireless signal coverage is necessary. Mobile Waiter communicates with the cash register via Wi-Fi. So your Wi-Fi network should meet these requirements:
•Independent (separated) Wi-Fi network not used by customers nor crew.
•Network visibility between the cash register and Mobile waiters from each network segment (cash register and Mobile waiters in the same Wi-Fi network).
•Stable coverage for all places used by Mobile Waiter.
•Support of Network Service Discovery (protocols DNS-SD (service discovery) + Multicast DNS (mDNS).
•Packet loss 10%, ping 10 ms
How does Mobile Waiter communicates?
To communicate between the cash register and Mobile Waiter independently through the IP addresses of devices, Mobile Waiter uses the service Android Network Service Discovery. By using this service Mobile Waiter automatically localizes the touch cash registers in the network and offers to connect them. The advantage of this solution is that the communication between the cash register and Mobile waiters does not depend on the IP addresses of individual devices. If the IP addresses of the cash register or Mobile waiters change, it will have no impact on the communication.
Alternatively, in Mobile Waiter you can enter the static IP address of the cash register. Then the Mobile Waiter will communicate with the cash register via this IP address. However, in this case you have to make sure that the IP address is reserved for this cash register and does not change.

The wireless connection coverage is fully managed by the customer and Dotypos disclaims any responsibility for it. The technical support covers only the basic functions of the application itself and does not cover any problems caused by inferior network quality. |
Network connection lost
If Mobile Waiter loses contact with the cash register or is out of Wi-Fi network coverage, the following notice will be displayed. In this case check whether the network coverage is functional and Mobile Waiter is connected to the right Wi-Fi network, otherwise return to a place covered by the wireless signal. Once the communication with the cash register is re-established, Mobile Waiter automatically restores its activities.
Each transaction made by Mobile Waiter is then transferred to the touch cash register to confirm it. So the data in all devices should be identical, even if a network outage occurs.
