  1. Dear all, I would like to send over Wifi 350Kb of data using the "WiFiClient.print" API. Could you please let me know what is the maximum length of data I could send in every POST? Is it possible to increase it? Thanks in advance. Best, George
  2. Hello again, I have connected the RedbearLab WifiMicro (http://discuss.redbear.cc/t/cc3200-wifi-micro/897/3) with a Real-Time Clock using I2C communication (SDA, SCL) and a sensor board using UART communication (Rx, Tx). When initiating the low power mode by using the api "goto_sleep(seconds)" should I also call the function "setupPeripherals()" and redefine the SDA, SCL, RX, Tx pins or this is just needed for the Digital In/Out pins? Thanks in advance. Best George
  3. Hello, Thank you again for your reply. I finally made working the MK20 usb dongle by updating the firmware with my laptop and then worked to my office PC. Regarding the upload to the WifiMicro after a lot of uploads and resets I finally uploaded code successfully with the following message which will be sent to the Energia by RedbearLab for debugging ...... Sketch uses 22,624 bytes (8%) of program storage space. Maximum is 262,144 bytes. Opening COM5 Can't open device Triggering bootloader....

  4. Hi, Thank you for your reply. I chose the correct port COM7 and then I pressed the Upload.
  5. Dear All, I am writing to you because I am experiencing problems with uploading code to CC3200 module. I have purchased the RedbearLab WifiMicro Kit (http://www.exp-tech.de/en/redbearlab-wi-fi-micro-kit) which worked for a few uploads but after that I had the following error: //--------------------------------------------------------------------------------------------------- Sketch uses 2,936 bytes (1%) of program storage space.

I cannot see the MK20 at the Com Ports anymore. So, instead of using the MK20 to upload code I used the FTDI Friend by Adafruit and I connected (GND, CTS, VCC, Tx, Rx, RTS) of the FDTI to the corresponding pins of the WifiMicro (GND, NRST, VDD, Rx, Tx, D13) http://discuss.redbear.cc/t/cc3200-wifi-micro/897. Unfortunately I am getting the following error in uploading ... Any help will be really appreciated!

  6. Thank you for your reply and your help. Best, George
  7. Dear All, I am interested in purchasing the following Wifi module based on CC3200 ... http://www.exp-tech.de/en/redbearlab-wi-fi-micro I have noticed that it can be programmed with Arduino like syntax using Energia. I have three questions please: 1) Is there any API to lower power consumption (hibernated mode) since I would like to send data every 2-3 hours? 2) I would like to send data over SSL and I noticed that it has a crypto engine. Could you please let me know if there is any API to upload certificates? If positive are there any examples in Energia? 3) I looked also at the Wifi examples of Energia 1.6.10 but I did not find any example with SSL. Could you please let me know if there is a library for SSL? Thank you in advance. Best, George
