How "reliable" should the connection be to PunchOut's LightBlue app?With -86dBm, I can connect to it ~40% of the time (other times it returns "no data" and goes back to the scanning screen)... below -93 dBm, I can see it, but I can't connect at all.A...
Is there a guidance sheet for the BlueNRG_Stack_Initialization_t structure passed into BlueNRG_Stack_Initialization?I've been using the SensorDemo application as a template, and found that I need to say#define MAX_NUMBER_ATTRIBUTE_SERVICE1 (13)Even t...
I wrote a version with 16 bit UUIDs, but it seems that LightBlue doesn't handle duplicate UUIDs in the same service (Service: Automation I/O; I added 4 analogs and 3 digitals; some are R/O and some are R/W, but LightBlue only is using the permissions...
