CC2564C: How to change ServerRxMTU？

Part Number: CC2564C
Other Parts Discussed in Thread: CC2564

I am using SPPLEdemo（STM32F4）， I want to change the ServerRxMTU to 185.I made the following changes but it didn't work.

/* GATT Configuration. */
#define BTPS_CONFIGURATION_GATT_MAXIMUM_SUPPORTED_MTU_SIZE (185)

This is the communication log I captured.MTU is still 0x83.How can I change the ServerRxMTU to 185?

Did, you try using the api, GATT_Exchange_MTU_Request()?

Please check the SPPLEDemo example.

Thanks

Thank you for your reply，GATT_Exchange_MTU_Request() is use in Master mode， My CC2564 works in slave mode。

The M-S in the above picture is sent by the mobile phone to CC2564. Request to change the MTU to 0x00B9，

CC2564 reply is 0x0083，How can I change the MTU of CC2564 to 0x00B9?
