Bluetooth for Dummies: Getting Data from SDP

As a result of effort in previous post we now armed with knowdledge what has to be done in order to connect to Bluetooth SDP (Service Discovery Protocol). All we need to get from SDP is a RFComm channel number to connect to, the rest information provided by SDP service while it is a subject […]

Bluetooth for Dummies: Establishing Connection to SDP

This post is a continuation of our endeavour to enhance USB Host 2.0 for Arduino library making a particular focus on SPP Bluetooth profile and Luminardo’s ability to initiate connection to a remote Bluetooth SPP-aware hardware. Last time it has been described what had to be changed in the library in order for Luminardo to […]

Luminardo + Bluetooth dongle: to be or not to be?

Our next goal would be to establish communication between Luminardo and ELM327 OBDII Bluetooth adapter like the one shown on the picture below. The adapter allows not to interfere with wires and therefore eliminates (or at least minimises) chances of running into problems with car’s onboard electronics, however, Bluetooth link adds up an additional complexity […]

Luminardo: USB Host Test

One of the most attractive features of Luminardo is its USB Host functionality built around MAX3421E chip and amazing USB Host Library for Arduino written and maintained by TKJ Electronics and by Circuits@Home. Today we are going to compile their library for our Luminardo and try to run a ‘quality test’ to make sure that […]
