Hello @JColvin,
I have tryied your method of getting to the command mode through phone app. I did exactly what you wrote, but nothink happens. I get into the command mode through usb-uart ttl converter with $$$ command. Then i send command SS,40 and PmodBLE reply with AOK. Then i confirmed that with command GK (as a pic. 1). I have also tryied command D and you can see that i have enable UART Transparrent service (pic. 2). Then I have tryied to get into the command mode with phone app, but nothink (I´ve also tryied reboot, but nothink works).
What am I doing wrong? I'm grateful to you for answers.
Thanks,
ivrsak
