Notes:
1. This module has an internal flash memory and a function to erase/sort unnecessary data if certain HCI commands
are issued and consume more than a certain level of free space in the flash memory. This operation occurs at every
module initialization (power-on).
If supply voltage becomes non-defined states during initialization or writing in flash memory, data in flash memory
might be destroyed. If the data in flash memory is destroyed, module will not work correctly. Therefore please be
sure to stabilize power source before /RESET release.
In addition please design module peripheral circuits to avoid temporary blackout of power source during operation.
Please refer
HD-AE-C 071063
for HCI command which rewrites flash memory data.
2. Input /RESET signal of 10ms and more in condition of VDD_3.3V at over 3.15V.
3. When the module is ready to accept the command, its module outputs the “0F 04 00 01 00 00” (Hex) USB to the
Data Line. After that, please access to the module.
4. The Typ. is a reference value. The value may change depending on the firmware version and conditions of use.
5. You don’t need to wait t6 if you confirm that this module has output “0F 04 00 01 00 00” (Hex).
