Lost of SoftAP binding when starting a new STA binding

[mytrain]

My application is using both SoftAP and STA as following:
-Smartphone connected via SoftAP to ESP8266
-Then each 2 minutres ESP connects using STA to my home WiFi router.

This issue is that conneting to STA kick out the Smartphone form the SoftAP as show in system debug

rm 1
state: 2 -> 3 (0)
state: 3 -> 5 (10)

@Links2004 gave an explanation of this issue a few days back: #119 (comment)
(i think previous comment down that link describes the issue similar to what you are seing).

@igrr
Thanks for the explanation. I assume that this is a hardware constraint and there is no change that ESPRESSIF is solving the issue one day.
I'll revisit my design to find a work around
