Hi,

I have improved the data throughput for peripheral devices by setting the connection interval to the minimum (7.5ms). I used long_characteristic example as a peripheral and hello_client is modified for sending long characteristic similar to the http_client example. But still the throughput is less than 8kbps, whereas the following discussion suggesting Re: Maximum BLE throughput for reliable data transfer  ~85kbps. What can I do to improve data?

Does a big MTU helps?

How can I get ride of application level ack?

What is the practical limit with two CyBLE013025 devices as central and peripheral?

For client-to-server transfers, please use the API void bleprofile_sendWriteCmd(UINT16 attrHandle, UINT8 *data, INT32 len) instead of void bleprofile_sendWriteReq(UINT16 attrHandle, UINT8 *attr, INT32 len).

For server-to-client transfers, please use the API void bleprofile_sendNotification(UINT16 attrHandle, UINT8 *attr, INT32 len) instead of void bleprofile_sendIndication(UINT16 attrHandle, UINT8 *attr, INT32 len, LEATT_NO_PARAM_CB cb).
