Hi,

wow I'm here again!

Simple code that I've had working on ESP32 & DA14585...

Basically this is the code:

uint32_t commands_val;

commands_val = 0x11223344;

wiced_bt_gatt_send_notification(conn_id, HANDLE_COMMANDS_VAL, 4, (uint8_t*)commands_val);

This is received incorrectly on my test environment (MacOS). The other platforms - ESP32 and DA14585 respond correctly. A temporary work around is to read the handle again if the value is what is expected, this then reads the correct value 0x11223344.

Any suggestions?

Thanks.

Hi,

uint32_t commands_val;

commands_val = 0x11223344;

wiced_bt_gatt_send_notification(conn_id, HANDLE_COMMANDS_VAL, 4, &commands_val);

Above implementation will work otherwise whatever you implemented in your response should also work.

You can check the API implementation in hello_sensor.c.

Ok, if I define "commands_val" as:

uint8_t commands_val[4];

and then:

commands_val[0] = 0x44;

commands_val[1] = 0x33;

commands_val[2] = 0x22;

commands_val[3] = 0x11;

wiced_bt_gatt_send_notification(conn_id, HANDLE_COMMANDS_VAL, 4, commands_val);

This works?
