CC2640: CC2640: Direct Test Mode HCI interface Setup

Part Number: CC2640

Hi,

I'm currently working on setup Direct Test Mode for 1M PHY testing.

Chip: CC2640F128.

BLE STACK version: 2.2.7.

IDE: CCS 7

RF Testing Software: BTool.exe

Binaries were built from Host_Test Project, according to the Direct Test Mode setup Instructions.

End Product binary is based on the Simple Peripheral example.

Now I have already made the UART available for 2 wire DTM testing, but when I was looking at the section 3 of the document: How to Do RF Radio Test With You Bluetooth Product: https://www.ti.com/lit/an/swra737a/swra737a.pdf?ts=1713364231908,

There are some of the Test Commands are missing, does that means I can't choose 1M PHY to test?

1. Missing HCIExt_EnhancedModemTestTxCmd and HCIExt_EnhancedModemTestRxCmd

2. Missing HCI_LE_EnhancedTestTxCmd and HCI_LE_EnhancedTestRxCmd.

Thanks!

Hello Mingxiao,

Thanks for reaching out. Could you please confirm if you are using ble5stack (ble5) or blestack (ble4) directory files from the SDK? HCIExt_EnhancedXXTestXXCmd() allows you to test for multiple PHYs, however it depends what ble version are you using (and BTool as well)

BR,

David.

Hello David,

Thanks for the reply.

I'm using this SDK: BLE-STACK 2.2.7, it's a bit of confusing not sure it's a BLE5 or BLE4,

BTool: v1.41.11(came with stack 2.2.7.). I also checked the CC2640F128, it supports LE 1M PHY. So does it means I will not be able to see those HCI commands?

Regard,

Mingxiao

Hello Mingxiao,

The stack supports BLE version 4.2, which implements only 1M PHY. On the other hand, BLE5 supports other PHYs (2M and coded) as well which are included in the EnhancedTest types. What test are you trying to implement?

BR,

David.

Hi David,

Thanks for the reply. That really resolve my concerns!

I'm trying to implement the 1M PHY testing.

Regard,

Hello Mingxiao,

Glad to hear that. Have you tried then the BTool version that comes inside the SDK?

The app note that you a referencing to uses cases from devices that work with ble5.

BR,

David.
