Other Parts Discussed in Thread: CC2640R2F

Tool/software: TI-RTOS

Hi,

There are some fw feature need to clarify:

1. Does CC2640R2F BLE 5 SDK have Peripheral sample code allow 2 smartphone(BLE central role) connected?? if no. if it possible to achieve this target without memory limitation???

2. If we use BLE 5 SDK sample code. Does the FW upgrade OAD must be off-chip??

    Hi Austin,

    1. More than one connection should be possible, it depends on the settings of the connection (parameters, pairing process, MTU, and data length pdu)

    2. We currently don’t have OAD examples for this SDK but due to flash limitations it will have to be offchip.

    hi Sean:

    Thank you for updated.

    If BLE need to use 2M data rate with max MTU and connected with 2 smartphone(one transfer data. the other one keep connection and idle). Is it OK for CC2640R2??

    Hi Austin,

    >> If BLE need to use 2M data rate with max MTU and connected with 2 smartphone(one transfer data. the other one keep connection and idle). Is it OK for CC2640R2??

    Again, this should be possible, but I really recommend selecting the phones that the end equipment is to support and do a quick test.
    There are many factors at play. You can enable heap profiling using HEAPMGR_METRICS and run tests against the various phones to see if the stack is able to run without running out of heap.
