Write custom characteristic value. | Cypress Semiconductor
Write custom characteristic value.
On a peripheral / server BLE, I acquire a value from one sensor and I want to store this value on a custom characteristic.
The CyBle_GattsWriteAttributeValue seem to be a good function and it need a connection handler as parameter, but I want to store the value even if no one (Central / Client) is connected to BLE peripheral.
Is possible, or attribute value can be updated only when connected ? how to do?
