hi
I’m having trouble with the Skywire cape lite. A Nimbelink GPRS module is plugged in.
I’m not receiving the OK response to the AT command (or to any other AT cmd) when I run
a basic tx rx application on the beaglebone. However I get the OK response when I’m
connected through a terminal (pico, putty).
If you are familiar with the cape it communicates through UART4. The cape also has a
uart grove connector connected to UART5 which I use to communicate with some other
module.
Here’s what I’m seeing =>
SETUP 1
- the grove connector (UART5) is connected to some other module
- pico is connected to UART4
- the app initializes UART4 as well
ACTION
- run the basic application
RESULT
- the AT cmd and OK response echoes on the terminal
- No OK response in the application
