Written values over BLE dont "stick"

[Anonymous]

i'm pretty new to Psoc development so please forgive any obvious mistakes.
i've been working on a project for the past few days. the values im writing with the CySmart applet dont seem to "stick."

   

looking at some of the example projects i came up with the following.

   

 case CYBLE_EVT_GATTS_WRITE_REQ:
             wrReqParam = (CYBLE_GATTS_WRITE_REQ_PARAM_T *) eventParam;
             if(wrReqParam->handleValPair.attrHandle == CYBLE_MULTFIBER_TOOL_DEVICE_CHAR_HANDLE){
                 CYBLE_GATT_HANDLE_VALUE_PAIR_T hvp;
                 uint8 theValue[2];
                 theValue[0] = wrReqParam->handleValPair.value.val[0];
                 theValue[1] = wrReqParam->handleValPair.value.val[1];
                 hvp.attrHandle = CYBLE_MULTFIBER_TOOL_DEVICE_CHAR_HANDLE;
                 hvp.value.val = theValue;
                 hvp.value.len = 2;
                 /* Report data to BLE component for sending data when read by Central device */
                 CyBle_GattsWriteAttributeValue(&hvp, 0, &cyBle_connHandle, CYBLE_GATT_DB_PEER_INITIATED);
                 }
          
             
             CyBle_GattsWriteRsp(cyBle_connHandle);
             break;

           

i've got a similar setup for the write without response, but when i write a value via the CySmart Applet it reads as the default value: 00
are there any glaring issues im overlooking?

so after some deliberation i found the answer.
the length of the value in the characteristic didn't match with the length of the value i was writing.
 

   

so if anyone else runs into this: check the length of your values
