CC2340R5: How to get RSSI with BTool

Hello Jerry,

I would suggest you look into this two guide materials:

• Application Note: How to Do RF Radio Test With Your Bluetooth Product.
• User Guide: RF Testing using BTool

BR,

David.

Hi David,

I find I will always get same RSSI level when I use HCI_ReadRSSI. Even if I change the distance of Central and Peripheral, RSSI didn't change, I think HCI_ReadRSSI is use to detect CW not the signal form Central. I think I need another command to detect the signal form Central.

Thanks.

Joe.

Hello Jerry,

Could you please share with me the steps you are following to read the RSSI value once you have established a connection between BTOOL (CC2340R5  running host_test) and basic_ble?

Are you passing the right connection handler?

If you want to try this using basic_ble running central role instead of BTOOl, you could use HCI_ReadRssiCmd(ConnHandle) to verify as well.

BR,

David.

Hi David,

1. Get BLE address from DUT (peripheral and it is customer FW, similar to basic_ble)

2. Use CC2340R5 EVB (central and fw is host_test FW) to connect this BLE address.

3.Use HCI_ReadRssi and it will get 0x7F(127), even if I change the distance of Central and Peripheral.

Hi David,

It's great. Thanks for your prompt support.

Hi David,

I can get different RSSI when I use the new SDK. Could I send those HCI command by TerraTerm or Putty? I need to use commands to complete RSSI testing instead of using GUI.

Hi David,

You might misunderstand Fu Yu. Fu Yu just need the HCI commands. They would not like to use BTool (GUI) to set HCI commands. So, they can clone the UART raw data from BTool log (show on BTool right window) and edit is as script file. Then use TeraTerm or Putty to send out this script file of HCI commands.  

Hello Jerry,

So the idea is to still use the UART and an image like host_test flashed on the device and just replace the GUI (BTool)? Then it is possible as well.

BR,

David

Hi David,

You are correct!

Hi David,

Is there anything updated?

Hi Fu Yu,

I think David agree my suggestion:

clone the UART raw data from BTool log (show on BTool right window) and edit is as script file. Then use TeraTerm or Putty to send out this script file of HCI commands.  

Hi Jerry,

When I use TeraTerm, I find I cannot enter any command. I need a SOP how to use HCI comman via TeraTerm.

hi FuYu,

First, you need to set HCI_Reset (0x01 03 0C 00) to CC2340R5. Please refer to below link.
