Luckily I haven't used it for an application where speed is important yet. Using in AP mode doesn't seem to make a difference.
I'm guessing it's the same with the AT firmware.Įven with that it still seems slower to load than it should be. I've been mostly using them standalone lately, rather than running AT firmware connected to a standard Arduino and there's a limit to how much you can send at a time, which I haven't found documented anywhere after a bunch of searching, I'm just sending it whenever it gets over 1000 characters long. What I found is you want to assemble as much as possible of your page at once and send it all at once rather than sending it in a bunch of small parts. I have incorporated a message along the lines of "be patient" that display immediately and then is hidden ones the rest of the page is downloaded and rendered.īut are there any other trick that people have used to speed up the process further?
#Esp8266 firmware update what baud rate download
I have used this web page to compress all my html and javascript:īut I am having trouble with my web page taking longer to download from the arduino than I would like - about 15 seconds or so.
Not sure if I was doing anything else wrong though. I did try setting the baud rate of the ESP higher than 115200, and in the setup function for the library, and I could seem to get the page to download from the arduino to my web browser.
#Esp8266 firmware update what baud rate serial
I've only used mine with hardware serial at 115200 just because that's the ESP8266 AT firmware default value and my application didn't require speed. I know people have reported issues using it at 115200 baud. That's only if you're using hardware serial, SoftwareSerial on the Arduino supports a much lower maximum speed.
I'm not sure if that will be reliable in real life. I hope that helps you and everybody who did the same and found your post over Google.The AT instruction set v2.0.0 documentation(from ) for AT+UART_DEF and AT+UART_CUR says:The datasheet for the ATmega328P shows the max baud rate is 2Mbps so I suppose that's the theoretical maximum. I had to set the baudrate to 115200 instead of 9600, and between the uploading files I had to disconnect the esp from power. After hours of searching I found a way to reset the bricked esp. I bricked my Esp with the same command, too. Maybe the AT+UART_DEF command - as mentioned by JRobert - works, but I used the AT+CIOBAUD=9600 command and it worked. I Connected an FTDI232 module at 115200 baud and could read the specs of the ESP8266 module now: AT+GMRĪfter that I sent the AT+IPR=9600 command, which first seemed to do the trick.īut after reboot of the module, all I got was garbage response, at any baudrate.ĭO NOT SEND AT+IPR=9600 TO YOUR ESP8266(12e) MODULE From now on, communicate with your device at 9600 baud.
#Esp8266 firmware update what baud rate software
I've been able to change my devices' baud rates from 115200 baud to 9600 over software serial you just have to expect garbage coming back and ignore it: // Set ESP8266 baud rate to 9600. What I've found using software serial is that it can push 115200 baud well enough to send commands to the device (though I wouldn't build an application that depends on it) but it can only read reliably up to 9600 baud. I have used these and can confirm that they work. The manual's prototype for the command is: AT+UART_DEF=,, ,, The baud rate commands are now "AT+UART_CUR" and "AT+UART_DEF" which configure the entire UART for the current session or the current and future sessions, respectively. Searches for either "CIOBAUD" or "IPR" in the current document (version 1.5.3) return no results. Depending on how recent a version of the AT Instruction Set interpreter your chip has, the two instructions you tried may not be valid ones they are not listed in Espressif's ESP8266 AT Instruction Set document.
