Table 9, Power Mode Register Settings
WĚ.232FHSS-25-R modules transmitting at high power in close proximity of one another may cause an increase in data loss. The Wi.232FHSS-250-R incorporates on-board AGC circuitry to mitigate this effect.

Default UART Data Rate: 2400 baud
Changing the value in regNVUARTDATARATE will change the default data rate at power-on. Changing regUARTDATARATE will change the current data rate. Before the module switches data rates, it will send a UART acknowledge at the current setting. Valid settings are:
