WI.232FHSS-25-R/ WI.232FHSS-250-R DATASHEET

Revision 1.1.0

4.1.33. Compatibility Mode (regCOMPATMODE)

regNVCOMPATMODE (0x25)

regCOMPATMODE (0x70)

R/W

Default Compatibility Mode: Disabled (0x00)

The Wi.232FHSS-250-R operates at a much narrower receive bandwidth (200kHz) than the Wi.232FHSS-

25 (600kHz). When the Wi.232FHSS-25 transmits, it deviates well outside the receiver bandwidth of the

Wi.232FHSS-250-R. To address this problem, v1.0.5 and later Wi.232FHSS-25 firmware and all

Wi.232FHSS-250-Rs support a compatibility mode. This allows both modules to communicate effectively

with each other.

When enabled (0x01), compatibility mode reduces the maximum RF data rate to 76.8kbps, reduces the

Wi.232FHSS-25’s deviation to 80kHz, and reduces the Wi.232FHSS-25’s receiving bandwidth to 200kHz.

All UART baud rates are supported, although the RF data rates associated with baud rates 31250, 38400,

57600, and 115200 will be diminished.

4.1.34. Auto Address Mode (regAUTADDMODE)

regNVAUTADDMODE (0x26)

regAUTADDMODE (0x71)

R/W

Default Auto Address Mode: Disabled (0x00)

When this register is enabled, the Wi.232FHSS-250-R module reads the Source Address from an incoming

packet and auto-populates this information into the respective Destination Address register. This ensures

that a subsequent transmission is sent only to the relevant module, in a point-to-point configuration.

The upper 4 bits of the volatile register contains the last-received packet type. The values of these four

bits are the same as the mode settings below. For instance, set regAUTADDMODE to 0x0F (Any Auto

Address), and then receive a MAC packet from another module. When you read back the

regAUTADDMODE register, the register value will be 0x4F. The lower 4-bits indicate the setting of the

MAC Address).

The table below summarizes the allowed values for the lower 4-bits of the register. The lower 4-bits

contain the value that controls the operation of this feature. The upper 4-bits are not read by the module

and are only written upon a successful packet reception:
