BLE PER Mode#

SiWx91x RCP Driver Supports BLE PER Mode Transmit and Receive functionality. Follow the steps below to verify both functionalities.

Follow the Compilation Steps in the above section and compile the driver as follows.
```
# make clean; make
```

Navigate to the release folder and run the following command to set the driver to PER mode:

# cd release
# insmod rsi_91x.ko dev_oper_mode=8 driver_mode_value=2 rsi_zone_enabled=0x601 
# insmod rsi_sdio.ko sdio_clock=50

BLE PER Transmit#

Run the following command to check the BLE PER transmit:

# ./ble_transmit <Access_Addr> <pkt_length> <ble_rate> <rx_channel_index><tx_channel_index> <scrambler_seed> <no_of_packets> <payload_type><le_channel_type> <tx_power_index> <tx_mode> <hopping_type> <ant_sel><inter_pkt_gap> <pll_mode> <rf_type> <rf_chain>
