BLE-Link/Bluno suggestions

bettydhughes wrote:Hey. I am attempting to match a Bluno Nano and a Bluno Beetle. As of not long ago I just figured out how to connection them with the Nano in focal and the Beetle in Peripheral. How would I continue to combine them? I didn't discover any data identified with the matching in the wiki. A debt of gratitude is in order for your assistance.

1. The timeout between + characters is very short so you need to cut & paste it to enter. It should accept +'s 100msec apart or so.
2. The AT commands should be case insensitive
3. A packet mode similar to the XBee modules would be very useful
