The application will automatically starts a TX continuous or a RX continuous according to the configuration given by the user.
Several parameters can be updated in main_tx_rx_continuous.c header file:
| Constant | Description | Possible values | Default Value |
|---|---|---|---|
TX_CONTINUOUS |
Only in modulated, the signal is sent in continuous transmission if true | {true, false} |
true |
RX_CONTINUOUS |
Only in modulated, put the chip in RX continuous mode | {true, false} |
false |
TX_MODULATED |
Signal is modulated if true other it's unmodulated | {true, false} |
true |
TX_SINGLE_INTER_DELAY |
Time in ms between two single transmission | uint32_t |
1000 |
TX_POWER_USED |
TX power in dBm | int8_t, range depends on radio configuration |
14 |
TX_POWER_OFFSET |
TX power offset in dB | int8_t |
0 |
TX_PAYLOAD_LEN |
Length of the transmitted payload | [0,255] | 51 |
LORAWAN_REGION_USED |
LoRaWAN used region | Value from smtc_modem_region_t |
SMTC_MODEM_REGION_EU_868 |
FREQUENCY |
Freq in Hz | uint32_t |
868100000 |
SPREADING_FACTOR_USED |
Spreading factor | Value from smtc_modem_test_sf_t |
SMTC_MODEM_TEST_LORA_SF7 |
BANDWIDTH_USED |
Bandwidth | Value from smtc_modem_test_bw_t |
