Expecting UART communications

I am working on this script with interaction with my firmware and apparently, it's not working as I expect it to.  Basically, I have a bare-bones firmware module that I initiate manufacturing tests via the uart command line.  I expect to see my prompt ">>" in which I then will send a command to initiate a test:

- ident: MTC-01

title: Load and Run Manufacturing Test Code

steps:

- command: identify nRF52

- command: erase nRF52

- command: program nRF52 softdevice.hex, zephyr.hex, NULL

- command: sleepms 5000

- command: uartCfg UART0 115200 8N1

- command: uartExpect UART0 ">>"

- uartcmd: uart UART0

send: "?\r\n"

- command: uartAwait UART0 10

My firmware emits via UART the following:
