HFP Unknown AT+CSRSF
Posted: Wed Jul 08, 2020 1:38 pm
I am using the hfp ag example, trying to connect to a Blaupunkt Bluetooth speaker that supports HFP. I'm getting errors from the BTM layer and unknown AT commands which google isn't throwing any hits for. Any ideas?
I'm also getting the following show up as and error, but I am assuming it isn't an error???
