Bluetooth BLE simple modem application

[anduss]

How easy is it to implement (or use) a simple modem-like interface to make a Bluetooth-replacement for a wired srial link between two instruments?

Like using a Bluetooth mosule with Nordic's 52832. Is it "native" or must it absolutely be "programmed" in the host's software?

There's the UART/Serial Port Emulation over BLE example that does exactly that for the Peripheral role, and there's a Client example Nordic UART Service Client as well.

The devices do not come with any FW programmed from the factory, they will need to be programmed during production unless you get a third-party to pre-program the devices for you.
