< Scan interval. This is defined as the time interval from when the Controller started its last LE scan until it begins the subsequent LE scan. Range: 0x0004 to 0x4000 Default: 0x0010 (10 ms) Time = N * 0.625 msec Time Range: 2.5 msec to 10.24 seconds Set scan interval (how often) and window (how long) in milliseconds

< Scan window. The duration of the LE scan. LE_Scan_Window shall be less than or equal to LE_Scan_Interval Range: 0x0004 to 0x4000 Default: 0x0010 (10 ms) Time = N * 0.625 msec Time Range: 2.5 msec to 10240 msec

Function Documentation

◆ disconnect_BLEClientNetworking()

void disconnect_BLEClientNetworking ( )

try to disconnect..

force saying it's disconnected

Definition at line 1007 of file BLEClientNetworking.cpp.

Here is the caller graph for this function:

◆ isConnectedBLEClient()

boolean isConnectedBLEClient ( )

returns whether connected over BLE as a client to a server(like a ESP feeder)

Definition at line 738 of file BLEClientNetworking.cpp.

Here is the caller graph for this function:

◆ loop_BLEClientNetworking()

void loop_BLEClientNetworking ( )

the loop()

a specialy display for now.. 1 = C connected BLE

try 4.22.22

note: https://github.com/espressif/esp-idf/issues/5105 Might address the error I see:

Here is the caller graph for this function:

◆ sendCommandBLEClient()

void sendCommandBLEClient ( String cmdString )

FOR NOW THIS IS HERE.. but it should be more generic. eg: sendBluetoothCommand() .. send the feed command

FOR NOW THIS IS HERE.. but it should be more generic. eg: sendBluetoothCommand() .. send the feed command NOTE: if we are a gateway (gen3) then this won't work, as it's not talking back..

if GEN3 then this handshaking will not work.. so just send the cmd, if longer than 1 character, it hangs .. so don't send

Definition at line 829 of file BLEClientNetworking.cpp.

Here is the call graph for this function:

Here is the caller graph for this function:

◆ sendCommandBLEClient_13orLess()

void sendCommandBLEClient_13orLess ( String cmdString )

send a string of 13 or less characters.

FOR NOW THIS IS HERE.. but it should be more generic. eg: sendBluetoothCommand() .. send the feed command

if (FeedFlag == true) flag is set in button_task Set the characteristic's value to be the array of bytes that is actually a string. this sets a value to the GATT which is the trigger value for the BLE server feeder

delay

check for the acknowledge from the server which is 0x01

Definition at line 877 of file BLEClientNetworking.cpp.

Here is the caller graph for this function:

◆ sendFeedCommandBLEClient()

void sendFeedCommandBLEClient ( )

sends the "feed" command over bluetooth to the connected device..

FOR NOW THIS IS HERE.. but it should be more generic. eg: sendBluetoothCommand() .. send the feed command

Definition at line 751 of file BLEClientNetworking.cpp.

Here is the caller graph for this function:

◆ setup_BLEClientNetworking()

void setup_BLEClientNetworking	(	char *	serviceName,
		char *	serviceUUID,
		char *	characteristicUUID
	)

the 'setup' for this module BLEClientNetworking. Here the service name is added (and potentially more later)

address to skip (for a number of times) .. how about 1 for now..

start the bluetooth discovery..

Initialize NimBLE, no device name spcified as we are not advertising

Set the IO capabilities of the device, each option will trigger a different pairing method. BLE_HS_IO_KEYBOARD_ONLY - Passkey pairing BLE_HS_IO_DISPLAY_YESNO - Numeric comparison pairing BLE_HS_IO_NO_INPUT_OUTPUT - DEFAULT setting - just works pairing

2 different ways to set security - both calls achieve the same result. no bonding, no man in the middle protection, secure connections.

These are the default values, only shown here for demonstration.

Optional: set the transmit power, default is 3db

+9db

Optional: set any devices you don't want to get advertisments from

create new scan

create a callback that gets called when advertisers are found

Set scan interval (how often) and window (how long) in milliseconds

Active scan will gather scan response data from advertisers but will use more energy from both devices

Start scanning for advertisers for the scan time specified (in seconds) 0 = forever Optional callback for when scanning stops.

Definition at line 56 of file BLEClientNetworking.cpp.

Here is the caller graph for this function:

◆ useBLEClient()

boolean useBLEClient ( )

returns if the BLEClient is turned on.. note, if connected to a BLE device, then disconnect
