Hello! I have a BlueSMIRTH Silver bluetooth module connected to an Arduino UNO. I am using the simple relay sketch shown in the https://learn.sparkfun.com/tutorials/us … -bluesmirf. I can enter command mode with $$$ just fine, and I can enter Get commands such as D and E and they report correctly. No errors at all. But any Set command I try always returns the string “ERR”. I have tried commands such as setting the device name “SN,ME” and a factory reset “SF,1” but they always return “ERR”. Any ideas what I am doing wrong? Thanks.
It’s been a while since I last used that product. If I remember correctly, it was very finicky about the line follower you used (like if your serial terminal emulator used a carriage return). Also, double check for the green(?) LED. Sometimes when I made changes, like to the baud rate… it would disconnect and I would have to enter command mode again.
Hi pidloop,
To expand a bit on Santa_Impersonator’s answer, the “ERR” print means an invalid command was entered. If you enter “D” and send, does it print the settings? It might just be that the commands you are sending are incorrect. If you are using Set commands, make sure you are formatting them properly with “SN, ”.
