I haven't used this core and bootloader for a long time, but AFAIK you don't need a serial port for DFU flashing. Try to select whatever COM port you have.

I hope it is not OT: ~I had similar problems recently. The Blue Pill did not work on my new computer with external USB hub. After a couple of hours...

I believe it is, there is a function `bool wifi_set_macaddr(uint8 if_index, uint8 *macaddr);` in ESP8266 firmware. But it is not implemented in this library. I searched more information and there...

The only reason is the limited memory on ESP8266. I think the number of connections could be rised up by changing the `MAX_SOCK_NUM` value in `wl_definitions.h` file. The same holds...

Strange, many internet sources say the ESP8266 can make 4 (or 5) connections at a time. I have just tested 32 concurrent TCPIP connections coming from 3 distinct IP addresses...

I did more tests - 16 concurrent clients running fine. https://gist.github.com/JiriBilek/7bdde1863a3340ad58cbebbcc080583e

Yes, it stops the client. Obviously, it must be stopped to be updated OTA. I haven't tried the code yet, it's a shame :(. Maybe jandrassy could help you, it's...

Hi, can you try to send e.g. 8 KB and see if the time is four times less (i.e. 2.5 s)? Next, as jandrassy wrote, check timings in your sketch....

I don't know if you are still interested in the issue, however, the long transmit times might be caused by sending short messages, i.e. sending one byte after another. The...

Do you want to make yourself the other side (master side) of communication? In that case you can obviously use the Arduino project (WifiSPI) as a start. I think you'll...
