I have just recieved a grove Serial Bluetooth WLS31746P. I have hooked it up to a grove shield and arduino. I have downloaded the library and the sample code and am just trying to upload the default sketch with no changes to see how it works.
I get the following error "conflicting return type specified for "virual void NewSoftSerial::write(uint8_t)’
do i have some old library or something? Any suggestions please?
