We are using ESP12E version and this interface with external host MCU via UART communication. We are able to send data to server using AT command, the following parameter and data size that we have used in our application.
1. Sending data size: 74Kbytes
2. AT command used: AT+CIPSTART using TCP, AT+CIPSEND, AT+CIPCLOSE.
3. External host MCU UART parameter setting:
flow control: diabled
For our critical problem is:
We are able to send this all data to server but it taking approx 1 minute for transmitting data to server. This problem is critical for us because our product is battery operated device using 2*1.5V AA size. So battery life is important feature in our application.
1. Why this taking too much time for transmission ?
2. Is any other parameter that i need to set in my code, Because we are communicating to ESP12E using AT command through UART?
3. What is the maximum speed for transmission data to server using AT cmd? Is any limitation?
4. Will you please suggest any best solution for increasing transmission speed to reduced this time improve battery life?
Looking forward your response..!!
We are still finding the solution for this problem, and until not get any help form here as well as from other espressif forum also.
I am waiting more for the answer of my question but still not able to give me solution ans well as suggestion for what should i do now?
Can anyone tell what is the maximum speed of ESP12E data transfer to server using AT command.
Is this module that i am using not able to transmit data fast, Should i need to change this module?
