ATE0--> Send Flag error: #0 #0 #0 #0 AT+BLEINIT=0-->AT+BLEINIT=0


(Pei Jia) #1

My test is just the hello_world from zephyr, and the CORRECT output from serial port should be:

Bench Clock Reset Complete

ATE0-->ATE0
OK
AT+BLEINIT=0-->OK
AT+CWMODE=0-->OK

***** Booting Zephyr OS build zephyr-v1.14.0-2842-g0440a815a91b *****
Hello World! hifive1_revb

However, I sometimes obtained the following output:

ATE0--> Send Flag error: #0 #0 #0 #0 AT+BLEINIT=0-->AT+BLEINIT=0
OK
AT+CWMODE=0-->AT+CWMODE=0
OK

***** Booting Zephyr OS build zephyr-v1.14.0-2842-g0440a815a91b *****
Bench Clock Reset Complete

What is Send Flag error? How to avoid this error?

Cheers
Pei

These messages are from the bootloader, sometimes it fails to initialize ESP32 module.
