I'm trying to figure out a way the Murata ZY module is set up. (1) Does anyone here can suggest, if it is shipped with BT stack installed? (2) If so, how do I 'activate' it? (3) If not, will purchasing Murata $300 dev board give me access to tools to install the BT stack on the module?
I only need the module as a wireless UART bridge, I do not need any custom application code on it, nor do I need to use GPIOs, OTP, serial memory or security features as long as it is possible to avoid it.
