Increasing scan time in Host test firmware

Vishal Nandanwar

Other Parts Discussed in Thread: CC2650MODA

Hello,

I am using host test firmware in my product. I am using default BLE settings for the same.

Default scan time there is ~10 sec, I want to increase it to 30 sec or one minutes. I tried to set parameter TGAP_GEN_DISC_SCAN using command set Param (0xFE30). But I could not set it or not able to conclude whether values got correctly set. I passed parameter value to 60000 in mSec (1 min = 60000 mSec). This is what(mSec) written in HCI vendor specific command documentation.

Is this the correct way/parameter to set the scan time?

Hi Vishal,

What API are you using to set this value? Are you using something like GAP_SetParamValue(TGAP_GEN_DISC_SCAN, 60000)?

Hi Katie,

I am using HCI command GAP Set Parameter (0xFE30) over UART interface. Passing the value 60000(int) in hex 0xea60 as parameter to the command.

I am using CC2650MODA on my host MCU, interfaced over UART. Hence using vendor specific command interface to communicate with the Host test firmware

Hi Vishal,

That looks correct to me. Did you try using GAP_GetParam to read back the parameter that you wrote, to see if it looks like it was correctly set?

Hi Katie,

I tried to set and read back the value. I found that values is getting set as 3100 only which is ~12.5 seconds.

Module is setting 3100 only, I tried lot more numbers to set. I tried to set 0x7530 which is 30 seconds, but module sets 3100 only.

Hi Vishal,

If you try a number smaller than 3100 is it able to set it? Or even then does the module return 3100?

Hi Katie,

Thanks for your support.

Actually there was an mistake at my side in length field. Length going towards the module was incorrect. After correcting it I could set any value to scan time field.
