    Cypress Read Event?

    tdbconsulting_1416776

      This question is for a Cypress BLE device configured as a Peripheral with a Custom Profile:

         

      When a Central BLE device writes to a Cypress Peripheral BLE device, the Cypress event handler API function (e.g. EventHandler(uint32 event, void *eventParam)) is called with the CYBLE_EVT_GATTS_WRITE_REQ event set. The value to be written may be acquired from the event handler parameter (e.g. wrReqParam->handleValPair.value.val where wrReqParam = (CYBLE_GATTS_WRITE_REQ_PARAM_T *)eventParam;). Apparently, the actual write is performed by calling the function CyBle_GattsWriteAttributeValue() and an acknowledgement response is sent to the Central device by calling the function CyBle_GattsWriteRsp(cyBle_connHandle);

         

      QUESTION:

         

      Is there such an event and functions for a Read?

         

      That is, is there, for example, a CYBLE_EVT_GATTS_READ_REQ event and CyBle_GattsReadRsp(cyBle_connHandle) function (or similar)?

         

      I ask this because the Microchip RN4020 has a Real-time Read feature (SR,40000000) that I would like to perform using the Cypress device. Microchip describes that Real-time Read feature bit as follows:

         

      "If set, the device request values from the host MCU through the UART and the host MCU must respond in a timely manner. If cleared, the device reads from the internal RAM of the RN4020 for the characteristic values that were previously set."

         

      Thank you all,
