Original question:

15.4 Stack Linux collector with coprocessor won't open PAN Network.

CC1352R: Unable to receive data from Sub-1GHz "Sensor" example using the "CoProcessor" example.

Hello!

I'm trying to connect and receive the data sent by a CC1352 running the "sensor" example, by using another CC1352 running the "coprocessor" example. However, I never receive the sensor data through the serial port.

P.S.: I am aware of the existence of a Texas Instruments-made example for running the "collector" example in a BeagleBone connected to a "coprocessor", however it is not 100% clear to me what exactly that code is doing, in terms of the bytes sent through serial communication.

Setup:

  • 1 CC1352 running coprocessor example connected through the serial port to a Windows PC running a Python script;
  • 1 CC1352 running the Sensor example.

I have developed the following Python 3 code to interact with the "coprocessor" example through the serial port. This is not the complete code, so, please, take this as just a pseudo code reference for what is happening. The code basically configures the "coprocessor", opens a network, accepts a connection and then "waits forever" (basically just printing out whatever it receives).

The last message you see (last line of the output) is, according to C:\ti\simplelink_cc13x2_26x2_sdk_3_10_01_11\docs\ti154stack\ti-15.4-stack-cop-interface-guide.pdf, a MAC_ORPHAN_IND, which I believe means the sensor got disconnected for some reason.

What am I missing here? Why does the sensor get disconnected? Why am I unable to receive the periodical sensor data?
