  1. So I have to figure out a way to connect my MSP430f5529LP to a local broker on a Raspberry Pi through MQTT. It is important that I use an ESP8266 as CC3100BOOST would cost me like $50 over here when I can get an ESP8266 for like $4. I went through various pages and stuff in search of codes and libraries and couldn't find a single one. This is part of my college project and I really need to get this done. Does anyone have any idea on how to work with ESP8266 for MQTT using AT commands as it is my last resort as I can't find any libraries for MSP430. And BTW, TivaC would also suffice. The b
  2. Hello everyone, I'm doing a project using Tiva C 1294 and ESP8266 for wifi connection. I have done with connect Tiva C and ESP8266 via Serial. I also tested with AT commands of ESP8266. My goal is to connect the Tiva C 1294 with Internet through Wifi ( not Ethernet connected). I've tested sucessfully the Temboo applications via Ethernet connected. However, when I change to ESP8266, I meet a lot of stucks. ESP8266 is using AT commands to connect to Internet. Therefore, it totally different from CC3300 ( I dont' have chance to use it). Energia doesn't support ESP8266 library. Hence,
  3. Hi, During the last two days I wanted to give Energia a try for performance testing of CC3200 based modules. On first glance TCP/IP performance is better than ESP8266 but I stumbled over many issues and currently I don't know whom to ask for: Energia, TI, RedBearLabs, ... I faced the same issues with either TIs original CC3200 Launchpad XL and RedBearLabs Wifi Mini module. Even if you only have comments, thoughts or solutions for a single one of my issues, please post your answer and reference to the issues numbered below. (1) First I was able to run the OutOfBox and blink exam
  4. The CEO of Espressif has confirmed on Facebook that the I/O pins of the ESP8266 are 5V tolerant . He also mentioned that the ESP32 and the ESP8285 I/O are also 5V tolerant. https://www.facebook.com/groups/1499045113679103/permalink/1731855033731442/?hc_location=ufi
  5. Hi!, I'm try to connect tm4c123gxl with esp8266: esp8266 tm4c GND GND VCC +3.3V CH_PD +3.3V Rx PD7 (Tx 2) Tx PD6 (Rx 2) I tested with "AT" command, if it's success, it will return "OK". Here is my code: void setup() { Serial2.begin(115200); Serial.begin(9600); Serial2.write("AT"); } //------------------------------------------------------------ void loop() { while (Serial2.available()){ char result = Serial2.read(); Serial.print("Serial2 result:\t"); Serial.print(result); Serial.print
  6. Hello ! I'm a student, I wonder if tm4c123gxl can write firmware to esp8266, because I see tm4c has Tx and Rx pins, or I have to buy a USB to TTL ? Here is my firmware I want to flash to esp8266 https://github.com/tuanpmt/esp_mqtt Thank you very much
  7. I'm thinking of making a little project linking the TM4C123 with an ESP8266 to send data to a network server. It's my first project in which I communicate with something else than sensors, so I was hoping to find some libraries/examples/reading materials etc. I found lots of stuff about CC3200, but nothing on ESP8266. There is really nobody around which played with this module? P.S.: I have found 8266 libraries for Arduino so I'll probably start with those
  8. In present work, I aim to control servo motor as an Internet of Things(IoT) so i use ESP8266 , which is the low cost wifi module (approx. 3$), to establish connection between Tiva LaunchPad(as a client) and Computer(as a server) via internet with Transmission Control Protocol (TCP). I use Java application to create server to control servo on the PC side of the project. One can see the Java Application in below video. Video Tutorial https://www.youtube.com/watch?v=2NBJP0-isrg Servo Motor: Micro Servo 3.7G (approx. 1.5$) WiFi Module: ESP8266 (approx. 3$) Source code (IoT.rar) can be
  9. I have ordered some ESP8266 modules and discovered you can flash the firmware in order to make it program over WiFi. This allows me to use the ESP8266 as a standalone IOT node. But to get the firmware on the ESP you need to flash it. As far as I can make out, the programming actually happens over RX TX and you need USB to Serial. As I'm not keen to buy stuff in double, I wonder if I can use the launchpad to program the ESP8266.I remember I've read somewhere that the BAUD rate is limited to 9600, but is it the MSP430 chip who's limiting it? f it's possible to do so, do I need to take some preca
  10. A non profit community forum for the new ESP8266 low cost WIFI IC is starting at www.esp8266.com, we are building a thriving community to highlight this new WIFI chip from Asia, come join us, we need all the help we can get :-) Thanks! Richard.
