I get the ERROR message when I send the command AT+UBTLE=1. I am trying to set the Bluetooth low energy role to Central. The firmware version on the Nina B112 is V1.0.0. Other commands work fine such as (AT, AT+FACTORY, AT+CPWROFF) so I don't think this is a UART problem or a syntax problem. The NINA B112 is surface mounted on a custom PCB and I am using the UART (RX/TX) interface with the CTS tied low. When I query the role I get AT+UBTLE:2.
The command succeeds with OK on the EVK (V3.0.1). Any insights into what is going on?
