Espruino uses the default clock rate - so you could either modify the Espruino library, or you could modify the Arduino one to stop it setting the rate away from the default.
First thing I'd try is to set Espruino's payload size to 32 bytes though - Espruino defaults to 16 but the module you link to seems to use 16.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
I'd perhaps try and compare:
