How could i go about changing the DHCP scope from 192.168.4.x to another subnet? I'm wanting to mimic a device but the app is hardcoded to a specific IP so i need to be able to change it ideally.

Thanks

'm ESP novice and would like to use multiple ESP8266.
Is there a way to change the default IP address 192.168.4.1?
So that i can use different ESP-Link units can respond.

Best regards

Did you ever figure this out as i'd like to change the ip and subnet ideally.

Hi everyone, struggling to follow the serial flash instructions on guit hub and get my ESP01 workling.

I'm using windows with ESP flash download tool v2.3
It has detected my device and reports 8Mbit.

The github site suggests

boot_v1.X.bin 0x00000
user1.bin to 0x01000
esp_init_data_default.bin 0xFC000
blank.bin 0xFE000

is that correct?

My esp was already programmed with (v0.9.2.2) firmware and running at 9600 baud, so I programmed at that speed. Firmware program appeared to complete fine (took a few minutes).

After removing reset jumper on my programming board and power cycling I see no wifi AP to connect to to proceed with initial configuration....
... help !

(yes I have a ~500mA 3.3V regulator)

Aside: Unlike the github instructions "esp_init_data_default.bin" is not in any of the .tgz releases I investigated. Had to downloaded SDK 2.0.0_16 to find it.

I have flashed esp-link to my esp-01 with 8MBit flash size. After power cycling the esp and letting GPIO0 float again, the device does not create an AP. Why is this? How can I connect to the esp when it does not create an AP?
