Macro Definition Documentation

◆ MY_RFM95_ENABLE_ENCRYPTION

#define MY_RFM95_ENABLE_ENCRYPTION

Define this to enable software based AES encryption.

All nodes and gateway must have this enabled, and all must be personalized with the same AES key.

See also: personalization

Warning: This driver always sets the initialization vector to 0 so encryption is weak.

Definition at line 2359 of file MyConfig.h.

◆ MY_RFM95_FREQUENCY

#define MY_RFM95_FREQUENCY (RFM95_868MHZ)

The frequency to use.

RFM95_169MHZ
RFM95_315MHZ
RFM95_434MHZ
RFM95_868MHZ
RFM95_915MHZ
Custom frequency in Hz

This must match the hardware version of the RFM95 radio. Additional information: https://en.wikipedia.org/wiki/Short_Range_Devices

Definition at line 855 of file MyConfig.h.

◆ MY_RFM95_MAX_POWER_LEVEL_DBM

#define MY_RFM95_MAX_POWER_LEVEL_DBM

Set max TX power in dBm if local legislation requires this.

1mW = 0dBm
10mW = 10dBm
25mW = 14dBm
100mW = 20dBm

◆ MY_RFM95_MODEM_CONFIGRUATION [1/2]

#define MY_RFM95_MODEM_CONFIGRUATION RFM95_BW125CR45SF128

RFM95 modem configuration.

BW = Bandwidth in kHz CR = Error correction code SF = Spreading factor, chips / symbol

CONFIG	BW	CR	SF	Comment
RFM95_BW125CR45SF128	125	4/5	128	Default, medium range
RFM95_BW500CR45SF128	500	4/5	128	Fast, short range
RFM95_BW31_25CR48SF512	31.25	4/8	512	Slow, long range
RFM95_BW125CR48SF4096	125	4/8	4096	Slow, long range

◆ MY_RFM95_MODEM_CONFIGRUATION [2/2]

#define MY_RFM95_MODEM_CONFIGRUATION

RFM95 modem configuration.

BW = Bandwidth in kHz CR = Error correction code SF = Spreading factor, chips / symbol

CONFIG	BW	CR	SF	Comment
RFM95_BW125CR45SF128	125	4/5	128	Default, medium range
RFM95_BW500CR45SF128	500	4/5	128	Fast, short range

◆ MY_RFM95_TCXO

#define MY_RFM95_TCXO

Enable to force your radio to use an external frequency source (e.g. TCXO, if present).

This allows for better stability using SF 9 to 12.

Definition at line 2364 of file MyConfig.h.

◆ MY_RFM95_TX_POWER_DBM

#define MY_RFM95_TX_POWER_DBM (13u)

Set TX power level, default 13dBm (overridden if ATC mode enabled)
