Hello, is someone here to help me combining some code to mbed? I have a javascript-code and an mbed-code, but I don't know how it works. Here are the two codes: micro:bit - Javascript-code let TimerForStandby = 0 let BTConnected = false bluetooth.onBluetoothConnected(() => { BTConnected = true led.setBrightness(64) basic.showIcon(IconNames.Yes) basic.pause(800) bluetooth.uartWriteString("AppOK") while (BTConnected) { basic.showIcon(IconNames.Yes) } }) function Repeater() { while (TimerForStandby < 2 && !(BTConnected)) { led.setBrightness(5) for (let i = 0; i < 10; i++) { basic.showIcon(IconNames.Happy) basic.pause(5000) basic.showIcon(IconNames.SmallDiamond) basic.pause(1000) } TimerForStandby = TimerForStandby + 1 } while (TimerForStandby > 0 && !(BTConnected)) { led.setBrightness(3) basic.showLeds(` . . . . . . . . . . . . # . . . . . . . . . . . . `) basic.pause(1000) basic.showLeds(` . . . . . . . . . . . . . . . . . . . . . . . . . `) basic.pause(1000) } } bluetooth.onBluetoothDisconnected(() => { TimerForStandby = 0 BTConnected = false led.setBrightness(128) for (let i = 0; i < 5; i++) { basic.showIcon(IconNames.No) basic.pause(100) basic.showLeds(` . . . . . . . . . . . . . . . . . . . . . . . . . `) } basic.pause(200) basic.showIcon(IconNames.Sad) basic.pause(1000) Repeater() }) bluetooth.startAccelerometerService() bluetooth.startUartService() TimerForStandby = 0 led.setBrightness(128) basic.showString("Test-Message") basic.pause(300) led.setBrightness(64) basic.showIcon(IconNames.Happy) mbed-code: /* mbed Microcontroller Library * Copyright (c) 2006-2014 ARM Limited * * Licensed under the Apache License, Version 2.0 (the "License"); * you may not use this file except in compliance with the License. * You may obtain a copy of the License at * * http://www.apache.org/licenses/LICENSE-2.0 * * Unless required by applicable law or agreed to in writing, software * distributed under the License is distributed on an "AS IS" BASIS, * WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or implied. * See the License for the specific language governing permissions and * limitations under the License. */ #include "mbed.h" #include "BLE.h" #include "BatteryService.h" DigitalOut led1(LED1, 1); Ticker t; BatteryService *batteryService = NULL; uint8_t batteryLevel = 50; void disconnectionCallback(const Gap::DisconnectionCallbackParams_t *disconnectionParams) { printf("Disconnected handle %u!\n\r", disconnectionParams->handle); printf("Restarting the advertising process\n\r"); BLE::Instance(BLE::DEFAULT_INSTANCE).gap().startAdvertising(); // restart advertising } void blink(void) { led1 = !led1; } void bleInitComplete(BLE::InitializationCompleteCallbackContext *params) { BLE &ble = params->ble; ble_error_t error = params->error; Gap& gap = ble.gap(); if (error != BLE_ERROR_NONE) { return; } gap.onDisconnection(disconnectionCallback); batteryService = new BatteryService(ble, batteryLevel); /* setup advertising */ gap.accumulateAdvertisingPayload(GapAdvertisingData::BREDR_NOT_SUPPORTED | GapAdvertisingData::LE_GENERAL_DISCOVERABLE); gap.setAdvertisingType(GapAdvertisingParams::ADV_CONNECTABLE_UNDIRECTED); gap.setAdvertisingInterval(1000); /* 1000ms; in multiples of 0.625ms. */ gap.startAdvertising(); } int main(void) { t.attach(blink, 1.0f); printf("Initialising the nRF51822\n\r"); BLE& ble = BLE::Instance(BLE::DEFAULT_INSTANCE); ble.init(bleInitComplete); /* SpinWait for initialization to complete.
