Title: bluetooth connectivity
Post by: ratcateme on August 09, 2008, 02:29:57 AM

Hi i have just purchased a axon and i want to know can i use this bluetooth Module http://www.robotshop.ca/ProductInfo.aspx?pc=RB-Spa-34&cf=273941a1 (http://www.robotshop.ca/ProductInfo.aspx?pc=RB-Spa-34&cf=273941a1) and connect it directly to rx and tx on the UART of the axon or do i need to put a rs232 shifter in the middle. i am just learning robotics and i have bought the axon as a way to make learning easier and i want to learn how to interface via bluetooth.

Scott.

Nope. Axon has UART stages, the module has UART stages. No RS232 shifting is needed.
However, the module has 3.3v signaling, which might be a problem (not sure if axon uses TTL levels or 3.3v levels)
