Error display on reset - Send Flag Timed Out Busy

Whenever I reset a program (with the button), I get the following Terminal output on COM7:

Bench Clock Reset Complete

ATE0–>Send Flag Timed Out Busy. Giving Up.
Send Flag error: #0 #0 #0 #0 AT+BLEINIT=0–>Send Flag Timed Out Busy. Giving Up.
Send Flag error: #0 #0 #0 #0 AT+CWMODE=0–>Send Flag Timed Out Busy. Giving Up.
Send Flag error: #0 #0 #0 #0

Followed by the expected display from the particular example program. I tried using a separate power supply of 7 to 10 volts on the power input connector but that made no difference. Could my ESP32-SOLO part be broken? I get no output on COM6. The fe310-g002 works and the JLINK debugger works.
