MQTTClient subscriptions not working
-
Just curious what I'm doing wrong here. LoPY4 1.19.0.b4
I'm assuming this is the client code: https://github.com/pycom/pycom-micropython-sigfox/blob/master/esp32/frozen/Common/MQTTClient.py
I can publish but I cannot get a subscription working.
The most I see is 'Packet sent. (Length: 4)' when publishing a message through broker when LoPY4 is subscribed.from MQTTClient import MQTTClient l99_serial = "abc" mqtt_client = MQTTClient(l99_serial, False, 4) mqtt_client.setLastWill('L99/{}/io/state/offline'.format(l99_serial), QoS=1) mqtt_client.configEndpoint('192.168.2.107', 1883) mqtt_client.connect(180) def mqtt_output_command_callback(ud,p=5): print('sub') print(ud) #mqtt_client.subscribe('L99/{}/io/OUTPUT/+/+'.format(l99_serial), 1, mqtt_output_command_callback) #mqtt_client.publish('L99/{}/io/state/online'.format(l99_serial), '', 1, False) mqtt_client.subscribe('L99/#', 1, mqtt_output_command_callback)

Well, whatever umqtt.simple works fine.
import machine from umqtt.simple import MQTTClient def mqtt_output_command_callback(topic,message): print('sub') print(topic) l99_serial = "abc" mqtt_client = MQTTClient(l99_serial, '192.168.2.107', 1883) mqtt_client.set_last_will('L99/{}/io/state/offline'.format(l99_serial), '', qos=1) mqtt_client.connect() mqtt_client.set_callback(mqtt_output_command_callback) mqtt_client.subscribe('L99/{}/io/OUTPUT/+/+'.format(l99_serial), qos=1) mqtt_client.publish('L99/{}/io/state/online'.format(l99_serial), '', qos=1) while True: machine.idle() mqtt_client.check_msg()```
