TEL0026 baud rate
tikiberserker 2012-03-03 15:32:55 2463 Views1 Replies I recently purchased a TEL0026 bluetooth module, and am having issues changing the baud rate. I am interfacing with an LM3S8962 (ARM) microcontroller dev kit. A few questions I have:
Are the AT commands listed in the datasheet case sensitive? (The datasheet is kind of all over the place)
Do the "/r" and "/n" count as one or two characters a piece?
Does the module stay configured in the new state if I power it off/on? I have to do a hard reset in order to get it to connect to my phone after switching out of AT mode.
Thanks for any help you can provide.

[i]Are the AT commands listed in the datasheet case sensitive? [/i]
Datasheet says "AT commands can be upper or lower case" right at the start of the AT commands section on page 4. Although it is still confusing having every other command be different.
[i]Do the "/r" and "/n" count as one or two characters a piece?[/i]
Don't definitively know the answer to this one, it may be specific to my uC, but I got it to work treating them as two characters a piece.
[i]Does the module stay configured in the new state if I power it off/on? I have to do a hard reset in order to get it to connect to my phone after switching out of AT mode. [/i]
You MUST do a hard reset (power cycle) after switching out of AT mode, both to leave AT mode and enable the new settings.
What really solved my problem, though, was on page 3, noticing that for AT mode the serial port runs at 38400 baud rate. DOH!
Amazing how much easier things can get with a little attention to detail. tikiberserker
