Sorry in advance if these are rather newbie questions, but I'm trying to use the PAN1740 to collect UART data and relay it to my end-device using the SPP profile but have no idea where to start. I know the PAN1740 implements the DA14580, but I don't know what version it implements. Some documentation says that the DA14580-00 does not support UART emulation profiles, while the DA14580-01 does. How do I know what MCU is in the PAN1740? After this, how do I get the profile onto the DA14580 (I bought the PAN1740 USB dongles, so I think I can use the JLINK to program it).
Also, I'm trying to design the PCB that uses this PAN module, but I'm having trouble deciding what pins connect to what. I poked and probed around the USB board with a scope to verify any data transmission coming from the UART pins of the DIALOG while I was loading firmware using the Dialog Connection Manager software, and never noticed any data flowing across the UART lines (using the USB dongle schematic as a reference). Does this mean the JLink only flashes the DA14580-* via the SWD pins? Should I connect them to my other MCU to flash the device on system bootup since I can't program the OTP without buying another programmer?)
Thanks for all your help.
