# BTstack port for Ambiq Apollo2 with EM9304

This port uses the Ambiq Apollo2 EVB with their EM9304 (AM_BLE) shield.
HAL and BSP from Ambiq Suite 1.2.11 were used together with the regular ARM GCC.
Upload is possible via the internal J-Link interface or the 10-pin Mini ARM-JTAG Interface.

## Debug output

printf is routed over the USB connector of the EVB at 115200.

In port/apollo2-em9304/btstack_config.h additional debug information can be enabled by uncommenting ENABLE_LOG_INFO.

Also, the full packet log can be enabled in src/btstack_port.c by uncommenting the hci_dump_open(..) line. The console output can then be converted into .pklg files for OS X PacketLogger or WireShark by running tool/create_packet_log.py
