I checked using logic analyzer there is no reply from the Notecard WiFi after sending this JSON string from TI CC1352R1 Launchpad UART.
{“req”:“note.add”,“body”:{“temp”:40.5,“humid”:60.23}}
According to this, there should be no problem with UART voltage levels.

The connection from TI CC1352R1 Launchpad and Notecarrier A is below.
TI CC1352R1 Launchpad UART RX ↔ Notecarrier A TX
TI CC1352R1 Launchpad UART TX ↔ Notecarrier A RX
TI CC1352R1 Launchpad GND ↔ Notecarrier A GND
Here is picture of my setup.
What am I doing wrong.?
I am able to communicate with the Notecard using Blues Wireless online serial console. But, I am not able to communicate with it using TI CC1352R1 Launchpad UART.
