I used ESP8285 in my design. From the datasheet I got that UART pins are GPIO1/3. But i didnt notice that AT-commands pins are GPIO13/15. Actualy there is no word in the datasheet about it. And we've already ordered 200 pcbs, but i pulled GPIO15 hard to the gnd under qfn package 8285.
I recompilled firmware. And as it is said here https://docs.espressif.com/projects/esp-at/en/latest/Compile_and_Develop/How_to_set_AT_port_pin.html I changed UART pins to GPIO3/1. And everything works fine. But when I connect to my Server, ESP throws this errors:
Code:
AT+CIPSTART="TCP","<ip>",23341
REUSEPORT FAIL
LINGER FAIL
CONNECT
OK
But everything works fine! Connecting/disconnecting, sending data..
Does anyone know what the errors are: REUSEPORT FAIL, LINGER FAIL? and why does esp work despite errors?
This is a commercial project, so, although it works, it is scary to send it to release with some errors ..
Start info from chip:
Code:
phy_version: 1163.0, 665d56c, Jun 24 2020, 10:00:08, RTOS new
module_name:WROOM-02
max tx power=78,ret=0
2.0.0
ready
Code:
AT+GMR
AT version:2.2.0.0-dev(875d40c - ESP8266 - Mar 31 2021 03:50:00)
SDK version:v3.4-rc
compile time(4920382):Apr 5 2021 18:02:09
Bin version:2.0.0(WROOM-02)
OK
Also, I downloaded my firmware to module WROOM-02 - the errors are the same and everything works the same.Statistics: Posted by Alehandro — Tue Apr 06, 2021 5:33 pm
