The application will automatically set the device in Ping-Pong mode.
The sample code will be used to perform test for both LoRa and FSK modem tests. Define macro PACKET_TYPE to SX126X_PKT_TYPE_LORA or SX126X_PKT_TYPE_GFSK (in file ../../common/apps_configuration.h) to enable each modem in the test.
The application can make device work as master or slave in Ping-Pong test. When starting up, it assumes to be a master and will send 'PING' packets and receive 'PONG' packets alternatively. When a 'PING' packet received, the device switches itself to slave mode, then send 'PONG' packets and expect to receive 'PING' packets. In slave mode, if the device receive a 'non-PING' packet, it will reset to master mode and start the previous process again.
Several parameters can be updated in ../../common/apps_configuration.h header file, refer to ../../common/README.md for more details.
Several parameters can be updated in main_ping_pong.h header file:
| Constant | Comments | Default value | Default value |
|---|---|---|---|
RX_TIMEOUT_VALUE |
timeout value for reception | Any value that fits uint32_t | 600 |
When compiling with arm-none-eabi-gcc toolchain, all these constant are configurable through command line with the EXTRAFLAGS. See main README.
