NV Parameters¶
NV11 - Feature Bits¶
The SM220 Series includes a power amplifier in its processing path, so the Power Amplifier Bit (0x0010) should be set via NV11 - Feature Bits. Clearing the bit to zero will significantly reduce your module’s transmission range.
NV64 - Vendor Specific¶
The SM220 Series is able to use the Turbo Mode Bit (0x0001) described in the ATmega128RFA1 NV64 - Vendor Specific section.
In addition, the Antenna Path Bit (0x0010) allows the SM220 Series to specify which antenna path should be used:
Value |
Antenna Used |
|---|---|
0 |
Compact F antenna (internal) |
1 |
U.FL antenna |
Note
Changes to the Antenna Path Bit (0x0010) do not take effect until you reboot the module. The setting persists through reboots and is preserved during a factory default.
