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?
