I want to buy some Bluetooth Modules but I have a question,
When I buy the CYBT-213043-02 module, not the CYBT-213043-MESH evaluation kit.
Do you need to load a bootloader or do a procedure to use it for the first time?
Hello ErVe_4649071 ,
The Boot code of module is in the ROM.
There is no specific first time procedure for CYBT-213043-02 .
If you are going to use the module in embedded mode, you can download the program via HCI UART pins. You may need a Recovery procedure prior to download. So better to incorporate Reset and recovery switch , HCI UART pins for download procedure.
