I just purchased Murata ZY Module and have UART lines, Vcc, Ground lines pulled out from it.
I am trying to flash the device using smart snippets through UART lines P02,P03 and also P04,P05.
But it is not working.
Is there any bootloader code or startup code that needs to be flashed on to the module before I can use smart snippets?
My main objective is it not use OTP for firmware and use external processor and serial bootloading.
