Hello folks, 

I have two questions about interfacng the KIT with RPi3.

 

1. I am trying to interface the Rpi3 and LTE Kit without the Micro USB as a shield. Is it possible to connect the two without actually using the USB? 

 

2. Also, I would like to know if it is advisable to turn off the WNC or entire AVNET board and restart it when needed to conserve power. I am using Sleepy Pi to put the Rpi3 into sleep after taking sensor readings and few images. I intend to transfer these reading and images using the LTE to my server and store it there. After this the entire system goes into sleep or power saving mode until the next sensor reading cycle. So, i would like to know if i can put the LTE board in power saving mode, if yes how to achieve it? 

Thanks !

Hi,

 

The 14A2A Shield works with the K64F Freedom board using some gpio pins and serial uart.  So you would need to study the WncControllerK64F and WncControllerLibrary for the details on how to use the gpio pins and the serial uart AT commands.  You would have to cross wire to the pins on the shield from the hat connector.  You would have to either port over WncControllerLibrary to the Pi or write your own code from scratch using whatever langauge allows you to manipulate the gpio pins and serial uart after learning the AT commands.  There is a document on ATT's website starter kit that lists the AT commands, you can also look at WncControllerLibrary found on ARM mbed's site: https://developer.mbed.org/teams/Avnet/

 

The easiest by far is going to be to use the USB port but nothing is impossible.

 

Regarding number 2, going to sleep can occur in various ways, see the ATT AT command document for setting up various power saving modes.  I will be clear here, unfortunately the power saving modes are not well documented, what is on the ATT site is what is currently available for info on this.

I'd also like to add to make sure you understand that the pins on the 14A2A shield are 3.3V (the 14A2A is actually 1.8V there are level translators in between that have to be enabled with the gpio pins); so that also needs to be taken into consideration!

 

Best regards

I subscribe to the questions of previous commentators. I am having similar difficulties installing the software. I work as a writer for this company https://expert-writers.net and I am a humanist, so I know a lot about technical issues, to my great regret.
