Re: More softAPs at once

I use SDK 2.1.0 AT commands. Now I use this method for checking a free channel for solve more APs at once: 1) wi-fi CHANNEL= 1 2) AT+CWMODE_CUR=2 (softAP mode) 3) If automatic reset caused by ESP module is captured within two seconds => CHANNEL++, AT+CWMODE_CUR=3, AT+CWSAP_CUR="SSID","...

Antenna PCB Layout Considerations

Hello, I would like to reach the maximum RF range for the ESP-12E module from esperessif. This module uses PCB Meandered Inverted-F Antenna (MIFA). What are the design consideration for the host module PCB layout ? 1) Should I place PCB FR4 material (without copper) under the antenna or should I bet...

Re: More softAPs at once

Please help, I have spent a lot of time by SoftAP configurations to test if more SoftAP can work in one area (one room). Although I can see all the ESP in SoftAP mode in the Wi-Fi Network Connection List in my laptop, it's not possible to connect all of them. Sometimes incorrect password is reported...

Re: Initial definition saved in Flash

I found some changes in the last 16KB flash area when I changed the initial definition. However, after change of the "esp_init_data_default" to user defined "esp_init_data_user" downloaded from a correctly set ESP flash on the address 0x3FC000 and upload the copy to the new ESP f...

Re: More softAPs at once

When I switched the second ESP device to softAP mode, it resets automatically. Maybe I have solved it. Now I enable DHCP in softAP mode with the "AT+CIPAP" empty. When I connect to ESP with my laptop, I can read IP address assigned for the laptop: "48.55.55.52" and mask "255...

Hardware flow control UART

Hi,
Is it possible to communicate between a host MCU and ESP12-E via UART using hardware flow control and AT+Commands ?

If so, do you have some connection diagram for GPIO RTS/CTS connection and software setup ?

Thank you,
Jan

Initial definition saved in Flash

Hello,

I would like to have station mode and enabled DHCP by default saved in flash (initial condition).

Is it possible to set initial condition for "AT+CWMODE_DEF=1" and "AT+CWDHCP_DEF=0,1" in flash download tool ?

Thank you,
Jan
