Hi, I am making a small box which can connect to my phone via BLE, I have one Da14580 basic kit, but the kit (with the debugger on it) is quite big for my box. Where can i buy a smaller module (which don't have a debugger on it) in order to solder it onto my PCB? the smaller Da14580 module must have antena on it because i cannot create the antena. the sample is in the attached file.
Another question, can i flash the program code into the SRAM or OTP using Serial Wire Debug (SWD)?
Looking forward to your replies. Thanks!!
