obniz is the technology for controlling IO, ON/OFF and UART/SPI/etc, from the internet through the APIs. No matter what the task is, it’s all done with a single program independent of connected devices and equipment. Adding or modifying devices, or manipulating services or characteristics can be done immediately without rewriting firmware.
obniz’s firmware-less technology integrates firmware and program on the server. You don’t need to develop BLE gateway firmware. Any operation can be completed by a single program on the server, without depending on the connected device or devices.You can add or change devices, manipulate services and characteristics, etc. immediately without rewriting the firmware.
You can utilize abundant resources without worrying about memory capacity because you can develop on the server. You can also develop on your PC without any host OS for development.
Only dedicated OS is inserted into the gateway. Even in the case that device is stolen, confidential information stored in programs and devices for manipulating BLE peripherals doesn’t leak out.
You can simply modify programs on the server to add and modify BLE devices. Remote handling and instant application.No more need to go to the site for updates or remotely write the latest program.

It can both read and transmit values such as temperature information contained in advertisements as well as beacon presence and absence, and scan and connect with BLE devices.
You can specify the UUID, Major, Minor, and RSSI strength, as well as "once sent, don't send for two minutes" and other programmatic settings.
It searches for beacons and BLE devices. It is possible to specify UUIDs, design free filters with javascript programs, format data and send APIs (HTTPS, MQTT, FTP, etc.). It is also possible to specify UUIDs and use javascript to design filters, format data, and send APIs (HTTPS, MQTT, FTP, etc.).

});
}
It can connect to BLE devices such as healthcare devices that need to be connected, and can acquire values and remotely control them in real time via the cloud. Up to seven devices can be connected at the same time, and while connected, the system can scan and search for devices sequentially. It can be easily programmed with library compatible sensors, so you can start your service today.
