ESP-WROOM-32 AT commands firmware
Re: ESP-WROOM-32 AT commands firmware
I tried to follow the steps to flash the ESP32-AT but seem doesn't work. I am quite confuse on the UART1 Tx and Rx pin number. Which pin number does it refer to? Is it the UART1 pin number on the ESP32 chipset?
Is there any full instruction on flashing the ESP32-AT and able to work?

it work's fantastic
chaning from
UART1 Tx
UART1 Rx
to UART0 pin list are here
http://espressif.com/sites/default/file ... ist_en.pdf
short view: and you can use your own pins, that you have to select then in component config -> AT
hope this helps
best wishes

Re: ESP-WROOM-32 AT commands firmware
hi,
If there is any solution to refresh joined devices IP? When I`m using AT+CWLIF as soon as I connect to station my smartphone it display IP address but it still appears whenever the smartphone is disconected.
Many thanks for any ideas

Re: ESP-WROOM-32 AT commands firmware
I have another problem and I don`t have any idea what I`m doing wrong. I can`t conect to the STATION from another ESP32 configured as a CLIENT.

hi pawel,
i am on the road just in time
see on first view a mistake last character
AT+CWJAP="ESP_MAIN_W","",
try without the last
AT+CWJAP="ESP_MAIN_W",""
cause you use no pwd
try this too
AT+CWJAP="ESP_MAIN_W"
let me know
best wishes

Re: ESP-WROOM-32 AT commands firmware
hi rudi,
When I`m using the terminal, everything works better.
When I`m using the AVR couple of things dosen`t work properly.
Most times I`m loosing the reception. Can`t find SSID name of the station on my celphone and another ESP32 modules.
As soon as I make communication through the terminal, most things works better. I`ve added the low ESR capacitor of 3300uF and ceramic 100nF but it doesn`t fix the problems.
I enclousure the picture of soldered modules.

hi pawel
how looks your line in AVR to send msg over UART to esp?
AVR_Uart_printf("AT+.......\r\n");
how you send the "

Re: ESP-WROOM-32 AT commands firmware
I`ve changed the ground and 9600 baudrate - at the moment works brilliant

Re: ESP-WROOM-32 AT commands firmware
Hello Rudi! thank you very much for your help.
In my las post i wrote twice that i've used the uart1. Actually in the second time i used the uart0 just like you do it.
and also not works
Can you send me your bin files? to check if i am making some mistake at compilation or is another problem.
regards

After reading your answer, i tried using the same serial program with the same configuration that you use.Component Config -> AT (using a usb-serial adapter)
*uart port number for AT command = 0
*uart rx pin for AT command = 3
*uart tx pin for AT command = 1
and also not works
Can you send me your bin files? to check if i am making some mistake at compilation or is another problem.

Re: ESP-WROOM-32 AT commands firmware
I think that the problem is the version of the esp-idf and esp-at-master example. the monitor console shows me:
And from what i could read in https://github.com/espressif/esp32-at/issues/6 and https://github.com/espressif/esp-idf/co ... a27e5bbdc7, a update may cause the problem. That's right?E (1826) wifi: esp_wifi_set_storage 1230 wifi is not init
W (1832) wifi: wifi nvs_open fail ret=4353
E (1835) wifi: wifi_init 1191 ret=4353
assertion "0 && "esp_wifi_init(&cfg)"" failed: file "/home/xcg/workspace/esp_iot_at/esp-at-application/components/esp-at-core/./at_port.c", line 560, function: initialise_wifi
abort() was called at PC 0x400f732f
