I have bluetooth module rn42 I need to configure it to 7-bit data mode. Data sheets says that I should use command S7,1 to enable 7-bit data mode, but it does not work. I receive ERR when sending s7,1 or s7,0. Also, i noticed that command SB,1 also returns ERR.
Module lists all available commands when you send him "H" command, and in my case commands S7, and SB, are not in the list… Maybe anybody has some more info about this strange case. I really need to make it work with 7 bit data mode. Firmware version is 6.15 Other commands works fine. Thanks for answers.
