Hi all,
I am kinda new when it comes to Bluetooth dev. I just got 2 of the br Le4-s3a and I am having trouble getting it working. Previously I have used the rn-42, and all it really took was powering it up to get it to work. At this point I just want to use it for some simple serial communication, and I didn't think I would need the dev kit. Do I need it to do anything though? I can power it up and one pio 2 flashes and led, while 5 is solid (I may have 2 and 5 mixed up). The device is not discoverable, and I have had no luck communicating with it via UART or i2c. Any ideas?
