Hi Martyn,

Thanks for testing the nxpwifi driver. On our side, we haven’t seen issues
with Bluetooth on the NXP i.MX93 EVK platform, regardless of whether the nxpwifi
driver loads the Wi-Fi-only firmware or the combo firmware.

From your logs, it looks like you're loading the Wi-Fi-only firmware
(nxp/uartspi_n61x_v1.bin.se). If it were the combo firmware, the btnxpuart
driver would skip loading the BT firmware entirely, since it would already
be downloaded by the Wi-Fi driver.

To help us reproduce and investigate further, could you please share:
- Your test platform (SoC, board, etc.)
- Your test steps
- The exact firmware version you're using
Also, have you tried running Bluetooth in a BT-only scenario (without loading
the Wi-Fi driver)? Does that work correctly?

Thanks,  
Jeff
