    27pF 100nF 2.5. Antenna ADEUNIS RF will assist you in your choice of antennas so as to optimize the performance of your products. Feel free to contact us for more information. We suggest the schematic below: • The footprint of the inductor and capacitor are useful to ensure good impedance matching between antenna and modules. The values will depend on the working RF frequency and characteristics of the antenna.

    NARROW BAND - NB868_25mW - User guide version V2.2.2 - Software version V2.3.0 3. Communication mode The RTU module is ready for transmission and reception operations at first power-up without any configuration effort required. It starts in communication mode allowing to directly sends and receive data. The default UART configuration is set to 9600bps, 8 data bits, 1 stop bit and no parity.

    NARROW BAND - NB868_25mW - User guide version V2.2.2 - Software version V2.3.0 When the number of octets in the buffer memory reaches the threshold of register S218 before the timeout of register S217, it is triggering on data. On the other hand, when the timeout of register S217 expires before the data in the buffer memory reach the threshold of register S218, it is triggering on time.

    NARROW BAND - NB868_25mW - User guide version V2.2.2 - Software version V2.3.0 4. Product Configuration - Command Mode The command mode is an embedded tool, accessible by the serial link via a terminal (*), enabling the programming of the module parameters using a set of instructions called: “AT command set”. AT commands are used to read and write the module configuration registers. In the com- mand mode, the radio is deactivated (in reception and transmission).

    NARROW BAND - NB868_25mW - User guide version V2.2.2 - Software version V2.3.0 The trickiest point is regarding the moisture sensitivity and the way to consider the module for the assembly on mother board. Considering the components on the module, we can define the module as a level 3 component, whose floor life under 60% max RH is 168 hours.
