arduinoesp8266nrf24l01
I have a prototype based on the ESP8266 wifi tranceiver as a standalone module, without any Arduino borad.
It works fine, but I have heard that the nRF24L01+ chip is less power consuming.
After some online research, I think there is no possibilities to embeed a program on the nRF24L01+, as it has no memory.
I just wanted to check in this forum if I am right or wrong.
(If I am right, there is no point considering the nRF24L01+ as I should also power the Arduino board)
How you have tested the module with computer? Is it in transparent mode? If the module is working as transparent mode it will convert wifi data to UART on your Arduino or PC UART port that's why it is called plug & play.
there is inbuit webserver on the nodule you can connect it to the PC through UART, and check with the WiFi Software test it. This way you can get idea whether it is working or not. You can make it work as STA or AP using the same software. Give it a little try.
I am not able to download manual. can you share it here so I can read and let you know the solution of your problem?
You connected your 3.3V regulator wrong.
Its pinout, as seen from the front, is Gnd/Vout/Vin:
You connected it as Vout/Gnd/Vin. Since its Vout is connected to ground, it's likely the regulator is passing its maximum current straight to ground. The same current also has to go through the 5V regulator, which has to drop at least 7V, resulting in a large power dissipation and the regulator getting too hot.
Also, neither your circuit diagram nor your wiring diagram show a ground connection between your power circuit and the rest of your circuit; your esp8266 will never work that way.

The nRF24L01+ is indeed just a tranceiver IC with no embedded firmware you can modify.
It has some capability to reduce the amount of work needed by the application controller (which can be any MCU, you can build your own ultra low power design if an Arduino is too power hungry), but the protocol stack has to be implemented there.
Maybe you want to take a look at the nRF24LE1 - which has integrated flash (16kB) and MCU (8-bit), but I don't think it's possible to fit a wifi stack in there.
There are similar solutions from TI and others around, which might be worth a look. Wireless stuff is advancing very fast these days, so I won't post any more specific stuff, as it will be obsolete on Monday.
