DA14683DSPS

Hi Dialog,

I'm using DA14683 DSPS peripheral connect with DA14585 DSPS host_dma. Two devices can make connection, but could not transmit/receive data. According to print message from DA14683, see as belows:

0> handle_evt_gap_connected: conn_idx=0000 address=80:ea:ca:de:ad:99 CI max is 24.
0> Peripheral updated CI min is 24, CI max is 24.
0> Peripheral exchanged MTU size is 247.

DA14683 will not run into case: BLE_EVT_GAP_DATA_LENGTH_CHANGED, and will not set SPS flow control ON.
What's the problem of this? And how could i transmit/receive data between DA14683 and DA14585. DA14683 works as peripheral , DA14585 works as Central.

Thanks & best regards!
Lionel

Hi liyehuan,

Hi liyehuan,

I am not completely sure if you are able to do what you are trying to accomplish, but let me check it and ask the Team, and then I will get back to you shortly.

Thanks, PM_Dialog

Hi liyehuan,

Hi liyehuan,

We have never tried to connect a 683 DSPS peripheral with a 585 DSPS central. There are some differences the way 68x and 58x DSPS handles the connection procedure. Let me check if it is possible to do that and I will get back to you.

Thanks, PM_Dialog
