I cannot understand this function "Cunstom_STM_Update_Char" regarding aci_gatt_update_char_value in BLE P2P template example.

[KKIM.6]

I'm following the P2P template example and I found that to send data using BLE, the example uses the Custom_STM_App_Update_Char function.

However, as I know the update API is aci_gatt_update_char_value.

So, I'm confused because the Custom_STM_App_Update_Char is only for returning the "aci_gatt_update_char_value()" with proper service channel setup.

in summary,

"Custom_STM_App_Update_Char" is only for returning proper "aci_gatt_update_char_value()"

Then, which command is conducting sending my data using BLE??
