  1. I was trying to load code for DHT11 temperature sensor in cc3200 simple link wifi launch pad but it was showing error that "failed to trigger boot loader" . Can i retrieve boot loader? or not and if yes tell how.
  2. I am trying to implement IoT in fall detection using CC3200. I am using u-blox neo-6m gps positioning module to acquire the location data. I am not able to get the correct coordinates from the gps module. Kindly help me with the interfacing of the module. I used SoftwareSerial.h library but the Energia compiler showed an error that this lib file works only with 8,16 and 20 hz devices.
  3. even after uploading the code to cc3200 launchpad interfaced with neo 6m gps module without any error the serial monitor does not display any values... can i know how to sort this out...
  4. There's a problem in interfacing Neo-6m GPS module with CC3200 MCU. I have to interface with Neo-6m GPS module with CC3200 MCU for getting the coordinates of a particular location. GPS module works fine when I interface it with Arduino UNO/Mega/Nano. Before I bought my own CC3200 MCU, I had interfaced Neo-6m GPS module with CC3200 at an Industrial training Institute and it worked fine there. Now, when I'm trying to interface GPS module with same configuration, setup and program, it shows nothing on Energia's Serial Monitor. Please check video (attached). Please let me know whether jumpers and wires are connected correctly. VID-20190629-WA0002.mp4
  5. Hello Everyone, I am planning on building an IoT robotic snow plow using a CC3200 Launchpad. Does anyone have suggestions on what camera module to use with the CC3200?
  6. I was using CC3200 to publish sensor data to a MQTT broker (iot.eclipse.org). I was trying on a demo where sensor data is received over Sub 1GHz RF and using CC3200 uploaded to the cloud via MQTT. Everything was woking fine like 7 days, but for the last 5 hours MQTT publish wont work, device is connecting to wifi though. This is a bizzare scenario I get no error while compiling, but I am getting a new warning: Description Resource Path Location Type deprecated conversion from string constant to 'char*' [-Wwrite-strings] Cloud_Gateway.ino /Cloud_Gateway line 138 C/C++ Problem for the line---------client.connect("myCC3200_gateway_maaislam"); & if(client.publish("mySensorData_maaislam",(char*)rxData)) Could this be a hardware issue or im missing something? Can anyone shed some light on the matter Please...I have also attached my .inofile with this post. Please note I am using energia sketch in CCS. (Same thing happens in energia as well ) Cloud_Gateway.ino.txt
  7. I am making a cloud-based attendance system in my database resides on a particular URL, which is stored at the string variable "server" according to the code. I have multiple WiFi networks in my organisation. I tested my whole system on one of the WiFi networks and I was able to connect to the server and push my data to the cloud. I had a meeting last evening and I had to use another WiFi network for which I entered the required credentials. My system successfully got connected to Wifi network but at the time of pushing the data to the cloud, it showed "Connection failed(to the server)". I tried that many times but no help. Then we thought of using the mobile hotspot. there the server worked fine again. What can be the issue? is the network anyway related to the server? Thanks in advance.
  8. Hello,. My idea is about connecting two CC3200 without a separate WiFi router like with their own like for example share it app which connects two devices using wifi one device with hotspot and one connected to that hotspot and share data.Is it possible to do that? As my idea is to share short text data between devices. using energia I want to continuously send/receive data between 2 cc3200 without any other modem unit or with another cc3200 which will be an access point between 2 of them. Is this possible ? If so , where should i begin? cc3200 (unit a) <-------> cc3200 (unit b) or cc3200 (unit a) <------via cc3200 (as AP) -------> cc3200 (unit b) Thank you
  9. I am using this example sketch to search for all WiFi networks: /* This example prints the Wifi shield's MAC address, and scans for available Wifi networks using the Wifi shield.

    Hi Frndz, Can anyone help me to interface CC3200 with LCD with clear pin configuration. Also the corresponding code in energia.
  14. Interfacing without I2C 1. browse for "Liquid Crystal" folder in C:\Program Files (x86)\energia-1.8.7E21\hardware\energia\msp430\libraries or on the path where you downloaded the energia. 2. copy the folder and paste it to C:\Program Files (x86)\energia-1.8.7E21\libraries. note that this library is made for MSP430. You need to follow the pin convention of cc3200 launchpad. 3. open energia and change the rename the pin number as one given in the launchpad schematic. Make sure you dont use the pins that are connected to push buttons. try using the pins that are less multifunctional. use 5V as Vcc for Vdd and POT for best results. for example, replace LiquidCrystal lcd(P2_0, P2_1, P2_2, P2_3, P2_4, P2_5); with LiquidCrystal lcd(8, 9, 12, 13, 14, 15); 4. There you go!. upload the code. interfacing with I2c best advantage of the I2C is only two pins are used for operation! Connect the LCD module to the I2C module. 1.download the library from https://www.arduinolibraries.info/libraries/liquid-crystal-i2-c . or if you have arduino, you can download the library from "Manage Library" looking for "LiquidCrystal I2C". 2. copy the library to the C:\Program Files (x86)\energia-1.8.7E21\libraries. make the necessary I2C connections 3. change the address from 0x20 to 0x27 and put 0x27,16,2., include the lcd library and upload the code. 4. comment out "WProgram.h" from the .cpp file if shows an error. 5. there you go!
  15. Hi I would like to utilize LPDS mode for CC3200. I am following TI SDK idle_profile_nonos example. However, since my code was developed in Energia environment, I am trying to add PM related functions into my code. However, it doesn't enter sleep mode. Here is what I did. I really appreciate if anyone who is familiar with LPDS can share their experience. One issue I can think of now is, according to TI, they mentioned that we need to set up SimpleLinkSyncWaitLoopCallback to put MCU to sleep when it is idle. However, I am not sure how SimpleLinkSyncWaitLoopCallback is invoked in Energia http://e2e.ti.com/support/wireless-connectivity/wifi/f/968/p/769004/2848594#2848594 1. I am using Energia IDE to develop my code. In setup(), I include PM Initialization struct platform_pm_ops lp3p0_pm_ops; /* Initialize the PM framework */ if (cc_pm_framework_init()){ Serial.println("Error: PM framework init failed"); while(1); } /* Get the SOC specific platform operations */ lp3p0_get_pm_ops(&lp3p0_pm_ops); /* Register PM ops with framework */ if(cc_pm_platform_ops_register(&lp3p0_pm_ops)){ Serial.println("Error: PM framework init failed"); while(1); } /* Register the interrupt with the global interrupt handler */ MAP_IntRegister(INT_PRCM, prcm_interrupt_handler); /* Enable the interrupt */ MAP_IntEnable(INT_PRCM); 2. In loop(), if GP28 is LOW, then I do the following if (sl_WlanPolicySet(SL_POLICY_PM, SL_NORMAL_POLICY, NULL, 0) < 0) { Serial.println("Error: unable to configure network power policy\n\r"); while(1);//LOOP_FOREVER(); } // set up gpio handler lp3p0_setup_power_policy(1); // 0: POWER_POLICY_SLEEP; 1: POWER_POLICY_STANDBY // just to clear any pending event _SlNonOsMainLoopTask(); set_gpio_as_wk_src(0, 0x3, 0); // WK_LPDS = 0x0, GPIO_SRC_WKUP = 0x3, PRCM_LPDS_HIGH_LEVEL = 0x0 cc_idle_task_pm(); 3. The functions above are directly from lp3p0_plat_ops.c. However, since I only want to use GPIO as the wake up source, I modify the interrupt handler as follows void prcm_interrupt_handler() { int status; /* Read the interrupt status, also clears the status */ status = MAP_PRCMIntStatus(); if (0 == status) { /* Invoke the wake from LPDS interrupt handler */ wake_interrupt_handler(); } else { } } 4. Since my wake up source is GPIO, I comment out Host IRQ and RTC portions in set_wkup_srcs May I know if I am missing anything else? Thanks, Dennis
  16. Hi I am developing a program for CC3200. The global variables in my program consumes quite an amount of space. As I continue to develop, I foresee there will be more space required. I am seeing the following from Energia compiler output. CC3200 has 1MB Flash. Both .text section and .bss section take 196KB. It seems like there is still space available. Is it possible to change the loader configuration to extend the address space of .bss section? "Sketch uses 35440 bytes (18%) of program storage space. Maximum is 196608 bytes. Global variables use 167124 bytes (85%) of dynamic memory, leaving 29484 bytes for local variables. Maximum is 196608 bytes. Low memory available, stability problems may occur." Thanks, Dennis

  19. Hello, I want CC3200 to act as an access point and server a webpage to give SSID and Password of a router. For this I am using SmartConfigexample in Energia. When I upload the code then it only shows " Starting WiFi SmartConfig" on Serial monitor. No AP appears. Is there something I might be missing? What should be the jumper setting while running this application on CC3200? Is there any relevant tutorial available for this example?
  20. Dear All, I want to interface an LCD to CC3200. Please suggest the name of lcd which can be used with cc3200 and energia. Regards, gunit
  21. I wanted to communicate my cc3200 with tms 57004 microcontroller using uart. So, I have connected uart_rx of tms 57004 to Uart_tx of 3200. uart_tx of tms 57004 to Uart_rx of 3200.
