Firmware
All One RF products are flashed at delivery with the standard firmware detailed in the manual. Moreover, some products support the very last version of the in-house firmware that allows Mesh networking. For specific applications, some further features can be implemented on demand. One RF Technology also designs and develops its own in-house ZigBee stack.
In-House ZigBee stack (Z-One Stack)
One RF Technology designs and develops its own in-house ZigBee stack. Our in-house Z-One stack, included in our ZigBee modules, is a certified Zigbee 2006 compliant stack.
Mesh lite firmware (M-One Stack)
The very latest in-house firmware is designed especially for constructing wireless networks. (Sensor networks, Irrigation, Home Control .) Within this type of network, all devices can communicate with each other using a robust address deployment protocol and a flexible hierarchy. The network topology can be set either manually or using a fully automatic engine, with auto-associate and auto-repair functionalities. Moreover, the Mesh Lite protocol supports an efficient low power mode, giving an excellent life length to battery powered applications. The upper layers of the firmware give access to standard functionalities like serial frames transmissions and telemetry mode. Moreover, it is possible to develop an application specific interface on demand.
Standard Firmware (S-One Stack)
The standard firmware is a universal and reliable answer to most of the radio transmission problems. This embedded software is most effective in cable links replacements, and provides the following features:
Hayes Mode
This smart mode configures and checks the module registers by 'AT orders' sent through the serial link or by radio. This mode replaces hardware switches and allows to change the module parameters without any diassembling. This feature is available only on our products.
Transparent Mode
It is a multipoint protocol. The radio module simply behaves like a half-duplex wired serial link. There is no flow control, and no encapsulation is needed on the serial data frames.
ACK (Acknowledge) Mode
It is a point-to-point protocol. On the radio side, data frames are encapsulated with a CRC, "verified" at reception and acknowledged, with retries in case of unsuccessful transmission. This mode offers an optimal radio link quality. A flow control is also performed on the serial link to avoid buffer saturation.
Addressed Mode
It is a secured mode with multipoint protocol. Each module has a Client ID and belongs to a Network. Serial data frames are encapsulated with the addressed Client ID. Only modules in the same Network can communicate with each other.
Client/Server Mode
It is an addressed secured mode where the Server manages RF communication to avoid collision. Data are sent in unicast (one to one) or broadcast (one to all) mode. No further management is needed within the client.
Telemetry mode
This protocol reads , sets or copies Inputs and Outputs between two devices or more.
Repeater Mode
A module in this mode repeats all it receives on a channel to another channel, and vice versa, doubling the range of the multi-channel devices. Non usable between modules in Client/Server mode.
Options
One RF in-house firmware can customized for a precise fit for a wide range of applications. Following are some examples of options develop by One RF:
Listen Before Talk
This functionality enables the module to listen to the radio channel before transmitting data. If the channel is not free, the module waits for a random amount of time before retry. This prevents radio collision.
Frequency hopping
All of our 915 MHz products already include this feature. In the 868 MHz band, the frequency hopping or the channel scanning can open the door for new types of applications, avoiding the use of secured modes.
Low Power telemetry
It is sometimes necessary, especially for sensor applications, to mix Telemetry with Low Power. One RF can also provide solutions to these problematic applications.
Custom firmware (C-One Stack)
Tailor made for a perfect fit according to customer demand.
