Hi,

I need to increase MTU size on CC2640r2f configurated as peripheral.

I tried several solution reported in the posts ( some say that it must be a central device to start this procedure) but none seems to work.

I have read that there is a project example: throughput_example_peripheral that maybe it can help me, but I cannot find it to download.

Can you tell me where I can find it? Or can you tell me a solution to extend MTU?

Thanks.

Best regards.

Giuseppe,

Throughput example can be found here:github.com/.../ble5apps

The maximum ATT_MTU is MAX_PDU_SIZE - 4. To change the PDU size, go to ble_user_config.h and change MAX_PDU_SIZE which will alter the MTU size. PDU/MTU size is negotiated at connection so you will need to make sure both your master and slave reflect the PDU size you want to support.
