Appli_BleSetUUIDCb,
};
The
Appli_BleSetTxPowerCb()
calls the aci function to set the power
aci_hal_set_tx_power_level(ui
nt8_t En_High_Power, uint8_t PA_Level);
By default, +4 dbm is configured in the nodes for BlueNRG-1 and BlueNRG-2; this can be changed by the user.
For
BlueNRG-1
and
BlueNRG-2
, the following different settings are available in the firmware:
/* MACROS for Power Level definitions */
#define POWER_LEVEL_LOW 0
#define TX_POWER_LEVEL_MINUS_18DBM 0 // = -18 dBm,
#define TX_POWER_LEVEL_MINUS_15DBM 1 // = -15 dBm,
#define TX_POWER_LEVEL_MINUS_12DBM 2 // = -12 dBm,
#define TX_POWER_LEVEL_MINUS_9DBM 3 // = -9 dBm,
#define TX_POWER_LEVEL_MINUS_6DBM 4 // = -6 dBm,
#define TX_POWER_LEVEL_MINUS_2DBM 5 // = -2 dBm,
#define TX_POWER_LEVEL_0DBM 6 // = 0 dBm,
#define TX_POWER_LEVEL_PLUS_5DBM 7 // = 5 dBm.
#define POWER_LEVEL_HIGH 1
#define TX_POWER_LEVEL_MINUS_14DBM 0 // = -14 dBm,
#define TX_POWER_LEVEL_MINUS_11DBM 1 // = -11 dBm,
#define TX_POWER_LEVEL_MINUS_8DBM 2 // = -8 dBm,
#define TX_POWER_LEVEL_MINUS_5DBM 3 // = -5 dBm,
#define TX_POWER_LEVEL_PLUS_2DBM 5 // = 2 dBm,
#define TX_POWER_LEVEL_PLUS_4DBM 6 // = 4 dBm,
#define TX_POWER_LEVEL_PLUS_8DBM 7 // = 8 dBm

UART interface on the firmware
The boards can be connected to a PC via USB connection. Any terminal software (HyperTerminal, Hercules,
Putty, etc.) can be used to open the serial communication port on the PC to check the messages from the board.
The UART of the controller on the board is connected to the PC via a VCOM (virtual communication) port. The
settings to open the communication port are:
•
Baud: 115200
•
data size: 8
•
parity: none
•
stop bits: 1
•
no hardware control
From the firmware main.c file, it can be seen that certain messages are printed to the VCOM
#if !defined(DISABLE_TRACES)
printf("BlueNRG-Mesh lighting demo v%s\n\r", MOBLE_VERSION);
printf("MAC Address = [%02x]:[%02x]:[%02x]:[%02x]:[%02x]:[%02x]
\n\r",bdaddr[5],bdaddr[4],bdaddr[3],bdaddr[2],bdaddr[1],bdaddr[0] );
#endif
After the board is connected and the terminal window is opened, press the reset button. If the firmware starts
successfully, the following messages are printed to the virtual com window
