Hello,
In my custom application I try to send a value several times in a fix interval (all 2 Seconds). For this purpose I used the command:
GATT_WriteCharValue(connHandles[DEV_TWO], &req, selfEntity);
The first time I call this command it returns a 0x0. I see on the connected device that tha message was received. Also the Bluetooth stack returns a ATT_WRITE_RSP without any error.
In all further calls the command returns the value 0x16 and it is not possible to send data.
Except the write command I do not call any Stack commands.
Can you please give me a tip how to fix this issue?
