Hi rajan22,
Τhe custs1 profile of the DA14585 SDK doesn't send a message towards the application level in order to indicate the read request, but if you apply the RI option in the database definition in the user_custs1_def.c file you could get the gattc_read_req_ind_handler() function executed. For example use the below line as a reference in order to activate this feature for the custom characteristics that you would like to get an indication when read:
// ADC Value 1 Characteristic Value
[SVC1_IDX_ADC_VAL_1_VAL] = {SVC1_ADC_VAL_1_UUID_128, ATT_UUID_128_LEN, PERM(RD, ENABLE) | PERM(NTF, ENABLE),
PERM(RI, ENABLE)|DEF_SVC1_ADC_VAL_1_CHAR_LEN, 0, NULL},
By doing that you will get the gattc_read_req_ind_handler() function to execute as soon as a central tries to read a specific characteristic. Please also check the implementation of the DISS profile which is using a similar option.
Thanks, PM_Dialog
