(async () => {
	await core.init('test');
	eventBus.on('paired', (from_address) => {
		core.sendTechMessageToDevice(from_address, {type: 'imapp'});
	});

	eventBus.on('object', async (from_address, object) => {
		if (object.app === 'BIoT') {
			if (object.type === 'hello') {
				n[from_address] = 0;
				core.sendTechMessageToDevice(from_address, {
					type: 'render', page: 'start', form: [
						{type: 'h2', id: 'n', title: 0}
					]
				});
				timers[from_address] = setInterval(() => {
					n[from_address]++;
					core.sendTechMessageToDevice(from_address, {
						type: 'update', id: 'n', value: {type: 'h2', title: n[from_address], id: 'n'}
					});
				}, 1000);
			} else if (object.type === 'close') {
				console.error('close', from_address);
				clearInterval(timers[from_address]);
