SPEEDUINO/SPEEDYEFI Bluetooth Guide

[@franksmith4254]

A lovely clear easy to understand video even I as a complete novice can follow.

[@ben_ide]

Great instructional video. Easy to follow, many thanks.

[@frankdoingthings8511]

this is grate thank you. i was thinking should i us this speeduino but i was a bit worried but after watching your videos i think i might go for this product. could you possibly make a video with you installing it inside the car too ? subed and liked

I have a question, why do I need to flip RX and TX after programming bluetooth module? I accidentally left mine connected RX to RX, TX to TX and everything is working fine.

[@toomanymiatas]

Really good question. I'm not 100% sure to be honest! Rx is short for reception, and Tx is short for transmission, so I think that's why it's transmission->reception, since the Rx pin is supposed to recieve data. In AT mode though you do end up reversing those and it still works, so perhaps it's not as important as I thought. I'm gonna do some digging and see what I can find.

@@toomanymiatas ok. P.s. nice video, helped alot :-) !

Can you put the actual code in the cooments... Can't see it on the screen and AT+BAUD Cones back with an error... Is there brackets or spaces or something that goes in there?

[@jiiizmo]

Did you have to use a sketch? I used a sketch code and the serial commander just goes crazy! Any ideas? I also made a video of the problem I’m having

[@toomanymiatas]

No sketch should be needed - you're simply using the Arduino IDE as a way to communcate with the Bluetooth module. No need to upload anything to the Arduino. Looking at your video, it looks like your problem comes the code you uploaded to the Arduino - you told the Arduino to print "LED off" whenever your flag is in a state of 0, and since it's always at 0, it's continually repeating LED off and spamming your serial monitor. Sorry it took me so long to reply!

I can't seem to be able to set a new pin. "AT+PIN1111" doesn't return anything. Also, the "AT" command didn't return anything which drove me mad trying to figure out why I can't connect. Turns out I can, kind of, becasue "AT+BAUD8" and "AT+NAMESpeeduino" worked. Just weird that the other two commands don't.

This is a great informational video if you don't mind the slobber sounds while he speaks. he just needs to back off the mic a little bit.

[@toomanymiatas]

I'll keep that in mind, I need a pop filter or something eventually.

FOR THOSE OF YOU SUFFERING WITH AT OK BUT AT+BAUD8 RETURNS AN ERROR: type in AT+VERSION into the monitor and if it returns a "3.0-xxx..." (x's being a bunch of numbers) ------------------------------------------------------------------------------------------------------ The AT commands appear to have changed for this different/newer version. Instead of AT+BAUD8 do: AT+UART=115200,0,0 (substitute 115200 with whatever baud rate you want) ------------------------------------------------------------------------------------------------------ To change pin, instead of AT+PIN you will use: AT+PSWD:"0000" you need the quotations, note its a colon instead of an equal sign (AT+NAME & AT+VERSION are the same and work btw) Dont know any other commands but if you know any useful ones comment them at me. This shit took me like 3 hours to figure out lol
