◆ connectToServer_BLEClient()

bool connectToServer_BLEClient ( )

Handles the provisioning of clients and connects / interfaces with the server

Check if we have a client we should reuse first

Special case when we already know this device, we send false as the second argument in connect() to prevent refreshing the service database. This saves considerable time and power.

We don't already have a client that knows this device, we will check for a client that is disconnected that we can use.

No client to reuse? Create a new one.

Set initial connection parameters: These settings are 15ms interval, 0 latency, 120ms timout. These settings are safe for 3 clients to connect reliably, can go faster if you have less connections. Timeout should be a multiple of the interval, minimum is 100ms. Min interval: 12 * 1.25ms = 15, Max interval: 12 * 1.25ms = 15, 0 latency, 51 * 10ms = 510ms timeout

[in] minInterval The minimum connection interval in 1.25ms units. [in] maxInterval The maximum connection interval in 1.25ms units. [in] latency The number of packets allowed to skip (extends max interval). [in] timeout The timeout time in 10ms units before disconnecting. [in] scanInterval The scan interval to use when attempting to connect in 0.625ms units. [in] scanWindow The scan window to use when attempting to connect in 0.625ms units.

Set how long we are willing to wait for the connection to complete (seconds), default is 30.

Created a client but failed to connect, don't need to keep it as it has no data

Now we can read/write/subscribe the charateristics of the services we are interested in

Try to get our new service == DEAD (for now.. this is not in the GEN3)

THIS IS A new ESP32 feeder

called to set a preference (which will be an identifier and a string, which can be converted to a number or boolean)

make sure it's not null

registerForNotify() has been deprecated and replaced with subscribe() / unsubscribe(). Subscribe parameter defaults are: notifications=true, notifyCallback=nullptr, response=false. Unsubscribe parameter defaults are: response=false.

Disconnect if subscribe failed

Send false as first argument to subscribe to indications instead of notifications

void disconnect_BLEClientNetworking ( )

try to disconnect..

force saying it's disconnected

◆ loop_BLEClientNetworking()

void loop_BLEClientNetworking ( )

the loop()

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

◆ scanEndedCB_BLEClient()

void scanEndedCB_BLEClient ( NimBLEScanResults results )

NOTE: this is called all the time... 4.22.22 –even if the "scan-stop" invoked.

Callback to process the results of the last scan or restart it

Definition at line 391 of file BLEClientNetworking.cpp.

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 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

Here is the caller graph for this function:

◆ sendCommandBLEClient_13orLess()

void sendCommandBLEClient_13orLess ( String cmdString )

send a string of 13 characters or less

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

Here is the caller graph for this function:

◆ setup_BLEClientNetworking()

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

the setup() and loop() passing the serviceName to look for..

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.
