ESP wont return to command mode after CIPSEND
Posted: Thu May 21, 2015 7:15 pmHi,
Using an ESP-03, I am just trying to send simple HTTP back to a web browser, see below...
Everything works perfectly, EXCEPT why do i get "busy p..." once i try to send AT commands after i close any open connections? The ESP becomes unresponsive until i cycle the power! Its baffling.
Many thanks in advance,
George (yet again!)
