I need to issue the proper AT commands to the BX3105 to put it into central mode, pair with an external wearable and get information from the wearable. I am having trouble with some of the commands that are in the AT command reference. They return ERROR. For example: Sierra Wireless Copyright 2018 BX310x.2.5.0-2 READY AT+SRBTSYSTEM=1 OK AT+SRBLECFG? OK AT+SRBLECFG=1 +CME ERROR: 916 How can I get some help? ---

I see that you are sending the AT+SRBLEADV=1. Doesn’t this mean that the iPhone is the central and the BX310x is the peripheral? I need to have the BX310x be the central ---
