CC2642R: Long Range connection issue with BTool

Part Number: CC2642R

Hi,

My target is to achieve BLE 5 long range connection with CC2642R launchpad. I am using simplelink_cc13x2_26x2_sdk_3_30_00_03 sdk and btool v1.42.16 with host-test app firmware. In one device I have flashed host-test-app image found in sdk and connect it with btool software, and with another launchpad i am using default simple peripheral code. When i trying to make connection with btool GUI, i am able to make proper connection upto 20meters, but after that i am not able to connect the peripheral launchpad. I am getting the device on scanning but when i tried to make connection i am getting below error.

But after making some changes when i tried the same with simple-central code in place of btool i am able to connect device properly.

#define DEFAULT_SCAN_PHY SCAN_PRIM_PHY_CODED

#define DEFAULT_INIT_PHY INIT_PHY_CODED

From this it seems BTool GUI not supporting coded PHY. How can i enable that in BTool? Can anyone please help here?

    Hi Aditya,

    I believe that coded PHY is supported in BTool. Are you able to connect to the simple_peripheral device with coded PHY using another device, for example a smartphone?

    Can you please explain a bit more what you mean?

    Hi Elin,

    Thanks for the reply,

    I have resolved the issue, After scanning from BTool GUI, I was trying to make connection through connection Establish button from GUI, which default supports 1Mbps PHY, But when tried to make connection from GapInit_connect command with enabled initPhyCoded, i am able to make proper connection from long distance.
