If I create a clean project using the SimpleBLEPeripheral I can connect to the CC2650 using LightBlue app on either OS X or iOS and inspect all the services/characteristics. If I add the preprocessor define MAX_PDU_SIZE=29 (or any value greater than 27), I can no longer connect to the device, I can see advertising packets but the connection is lost if I try to connect to it.
Using the Packet Sniffer I can see the central device sending a ClientRXMTU packet but there is no response from the CC2650 and no response at all after that. Has anyone successfully managed to increase the size of the MTU?
