IOT Malaga

 We have acquired this GPIO extension board, thats allow a quick connection of the raspberry GPIO connector into our bread board for quick prototypes. We continue creating python programs that have connection to the network, and we are able to API control the different sensors/leds/servo-motors/reles, etc Today we tested a very simple web browser to control the status of a LED via internet. Next steps to send/receive commands via MQTT, access via WEB/API, send commands to the UICC via AT+CSIM commands. We can read/update files inside simcard for a full secure environment. Specific files in the simcard can be a mapping of the status of the different sensors.

 Hello, after the great success of yesterday, on which we managed to send APDUs to the UICC via AT+CISM commands. Today we have sent a 3.40/3.48 envelope to the UICC via AT+CSIM. Envelope was prepared with the right otakeys, counter, etc. File inside the simcard was updated!! In the mean time we are also playing with python and basic led and switch test programs.

 YES!! AT+CSIM commands are working fine. Our linux board is able to send APDUS to the simcard with success. Below commands to read standard file ICC. Until here is the work I can publish. Complex communications with javacard applets falls inside the intelectual property of my company and I cannot publish. This will be published in internal company confluence pages. We have also been able to send text sms, but that is easy peasy :)

  Our IOT devices have WIFI and GSM connectivity. It will try first send data WIFI, if no connection, it will start the GSM!!

 De nuevo gracias emnify por las tarjetas SIM recibidas de forma gratuita. Son tarjetas SIM que se conectan a la red de datos en cualquier pais de forma automática. En el plan gratuito tenemos gratis 10MB. Y mi IOT gasta 1KB por cada request con info de los sensores. Si envio un request cada hora, al día gastaría 24KB= 24.000bytes Si no me equivoco 10MB son 10.000.000 de bytes Dividiendo 10.000.000 / 24.000 = 416 dias!!!!   Amigos, recordad no conectar las sims a un teléfono movil; ya que se conectaría rápidamente a la red, y todas las apps y servicios empezarían a hacer uso de la red, y te podrias gastar el bono de 10MB en segundos.

Hola, la verdad que no es nada del otro mundo. Usando una libreria whatsAPP para nuesto ESP32, pues me llegan directo a mi mobile los whatsapp con alertas y lecturas de mis sensores. Hello, to be honest this is not difficult, and not implemented by myself. I am using a library forwhatsApp for our ESP32 IOT board. Now I am receiving alerts and sensor reading directly in my mobile!!!  

 SI!!!! Podemos enviar APDUs a la tarjeta SIM como si la sim estuviera conectada a un smart card reader. Esto facilita mucho las cosas y podremos realizar operaciones con los applets de la javacard. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fref_at_commands%2FREF%2Fat_commands%2Faccess_uicc%2Fcsim.html Dar las gracias a Nordic Semiconductor por enviarme 2 tarjetas modems IOT para evaluación. YES!!!  we can send APDUs to the simcard like if the sim is connected to a smart card reader. This will easy a lot the project, and we could be able to send commands to applets in the sim javacard. https://infocenter.nordicsemi.com/index.jsp?topic=%2Fref_at_commands%2FREF%2Fat_commands%2Faccess_uicc%2Fcsim.html Thanks very much to Nordic Semiconductor for sending a couple of IOT modems for evaluation.
