[ x] Bug or issue with library functionality (ie, sending data over TCP/IP) [ x] Question or request for help

Trying to Connect to broker.hivemq.com and update ledstatus. Connection is successful but the incoming data is not handled correctly and ledstatus does not update.

This code worked fine for many weeks until 3 days ago. Tried deleting library and installing various versions through IDE but to no avail.

Problem Experienced-how to process following incoming data? : '### Unhandled: +CIPRXGET: 1,0 ' Could these foreign characters be an issue for CIPSEND and RXGET(See Serial Monitor Output Below)? Example. '>MQTTGsmClientTest '

Currently working with:

[11660] ### TinyGSM Version: 0.10.9 [11660] ### TinyGSM Compiled Module: TinyGsmClientSIM800 [11844] ### Modem: SIMCOM SIM868 [11844] ### Modem: SIMCOM SIM868 Modem Info: SIM868 R14.18 Main processor board: ESP8266 TinyGSM version: TinyGSM Version: 0.10.9

Code Used: MQTT Client Example Code

`/** *

For this example, you need to install PubSubClient library:
https://github.com/knolleary/pubsubclient
or from http://librarymanager/all#PubSubClient
TinyGSM Getting Started guide:
https://tiny.cc/tinygsm-readme
For more MQTT examples, see PubSubClient library
Use Mosquitto client tools to work with MQTT
Ubuntu/Linux: sudo apt-get install mosquitto-clients
Windows: https://mosquitto.org/download/
Subscribe for messages:
mosquitto_sub -h test.mosquitto.org -t GsmClientTest/init -t GsmClientTest/ledStatus -q 1
Toggle led:
mosquitto_pub -h test.mosquitto.org -t GsmClientTest/led -q 1 -m "toggle"
You can use Node-RED for wiring together MQTT-enabled devices
https://nodered.org/
Also, take a look at these additional Node-RED modules:

Hi

Could someone possibly assist with this? Having a difficult time trying to resolve.

SRGDamia1 commented 3 years ago

Try using the TINY_GSM_YIELD.

imamminer commented 3 years ago

Hi

Try using the TINY_GSM_YIELD.

Hi

Thanks for this suggestion. It appears to have resolved the issue!

regards

SRGDamia1 commented 3 years ago

Great!

imamminer commented 3 years ago

Hi

is it possible to re open this thread as the solution seems intermittent?

the mqtt broker connects successfully but the gsm rxget data is not read correctly possibly because of some foreign characters the square box characters "" or question marks. so the result is that i do not receive MQTT topic "Message Arrived" data and the LED does not turn on or off.
