UART - BLE project, CyBle_GattsNotification()
I'm developing an application based on this UART TO BLE BRIDGE project:
When data com from the UART interface, function CyBle_GattsNotification() is used to send data to the Central device.
For small frames ( tested with 15-16 bytes), it's works well.
For bigger frames ( tested with 24 bytes ), CyBle_GattsNotification() return an error ( CYBLE_ERROR_INVALID_PARAMETER ).
- My MTU is bigger than 24 ( actually 300 set on GAP settings , BLE component )
- Data characteristic size is bigger than 24 (30)
Do you have any idea about this problem ? Why i can't send more datas ?
