CC2340R5: is there any event from HCI to manage flow control

Hi,

Thank you for reaching out. To clarify, you are asking if there is an event that is sent from the peripheral to the central when its queue is full?

Best Regards,

"Is there any HCI event ( memory full event  ) sent from BLE stack to application for managing flow control of data".

   aim asking about any Event sent from BLE stack to application.

Hi,

Understood. Almost all HCI commands executed by the stack will send an HCI complete event to the application which will contain information regarding the command executed and the status of the command.

Thanks for quick reply.

May i know where can i get memory full event sent from HCI so that i can use it for flow control

Hi,

Can you clarify which memory you are referring to? Would this be the entire device RAM, the system stack, the ble heap?

Best Regards,

Hi Jan,

    Whenever we send notification/Indication hope we use ble heap.

Assume we try to send notification/indication faster than HCI and now HCI is out of buffer, and now if HCI sends me an event

so that i can stop sending indication till HCI says he has buffer to send it to central.

Hope i made it clear

Hi,

Understood. In that case, if the HCI buffers are full, then I would expect the return code MSG_BUFFER_NOT_AVAIL to be returned. If you are directly calling ble APIs, then the blePending return code will be provided instead.
