Tool/software:

Hi All,

I am using the CC2654C module with stm32f4 MCU, and using the BLE stack CC256XSTBTBLESW_5.1.1.1

By FCC test result , I found the Tx frequency may Offset around 250kHz, I would like to asking if there any command or API can correct the radio offset.

if the API / command exist, does any reference or example.

if there is no API / command , How to correct the radio frequency offset issue ?

Thanks a lot

Hi,

TI does not have a cc2564C module do you mean the EVM (Blue board?) or are you using a third party CC2564C module.

Since you have asked about the service pack I believe this could be the reason of the offset as seen on this e2e thread

https://e2e.ti.com/support/wireless-connectivity/bluetooth-group/bluetooth/f/bluetooth-forum/632013/cc2564modn-tx-frequency-shift-by--1-mhz-for-le-and-classic

Please load the service pack first either in the testing script or with bluetopia stack

Best,

Rogelio

Hi,

I would like to asking the service pack guide document in the post.

the user guide link was lost.
