Installing rookie sideloader

Unfortunately it only works on windows, guide for linux:

Loading rookie sideloader on Linux:

If someone still needs this to work in Linux, just set up a Windows virtual machine(I used Virtualbox) open Rookie, click activate Wireless ADB, then No for manual config, put in the IP of the Quest. That worked for me. Network Adapter has to be configured as bridged, not NAT.

Edit: turned out it only works if you first connect in linux to sidenoder with cable, then activate wireless there.

QoS Level	Benefits
QoS 0	- Lowest overhead
	- Fast message delivery
	- No guaranteed message delivery
	- No message retransmissions
	- Suitable for non-critical data or real-time updates
	- Minimal impact on network bandwidth
	- Simple and efficient for scenarios where message loss is acceptable
QoS 1	- Ensures at least once delivery
	- Minimal message duplication
	- Suitable for scenarios where some duplicates are acceptable, but loss is not
	- Guarantees that messages are not lost
	- Requires acknowledgement (PUBACK) for every message
	- Provides a balance between reliability and efficiency
QoS 2	- Ensures exactly once delivery
	- No message duplication
	- Suitable for mission-critical and highly reliable applications
	- Guarantees that messages are not lost or duplicated
	- Most reliable but involves more overhead
	- Requires a complex handshake (PUB, PUBREC, PUBREL, PUBCOMP) for every message

 Connecting to mosquito TLS

I successfully established a secure TLS/MQTT connection between a publisher, a broker, and a subscriber. Here's the step-by-step procedure I followed:

1. Generate a private key:
   openssl genrsa -out client.key

2. Generate the Certificate Signing Request (CSR):
   openssl req -out client.csr -key client.key -new

3. Submit the CSR content to test.mosquitto.org/ssl/ and obtain the "client.crt" file.

4. Download the "mosquitto.org.crt" from test.mosquitto.org/.

5. Ensure all the following files are in the same folder:
   - client.crt
   - client.csr
   - client.key
   - mosquitto.org.crt

6. To publish, use the following command:
   mosquitto_pub --cafile mosquitto.org.crt --key client.key --cert client.crt -h test.mosquitto.org -m "Hello World" -t "test" -p 8884 -d

7. On the subscriber side, use the following command:
   mosquitto_sub -h test.mosquitto.org -t "test" -p 8884 --cafile mosquitto.org.crt --key client.key --cert client.crt -d

I followed this procedure on my Ubuntu PC, and the TLS/MQTT connection is working flawlessly.

Logging Levels

System logger

$ journalctl --unit=service

$ journalctl -fu service # To follow log as with tail -f

 
To limit journal logging:

$ sudo nano /etc/systemd/journald.conf
Uncomment
SystemMaxUse=100M
sudo systemctl restart systemd-journald

$ journalctl --disk-usage # How much space is used

Restart system logging
$ sudo systemctl restart rsyslog # resets /var/log/syslog, deamong.log
$ sudo systemctl restart logrotate

/usr/sbin/logrotate -f /etc/logrotate.d/spaikon # Force run logrotate

Show detailed debug trace
from loguru import logger
@logger.catch # Stack trace

Python logger

When a logger is created, the level is set to NOTSET (which causes all messages to be processed when the logger is the root logger, or delegation to the parent when the logger is a non-root logger).


Note that the root logger is created with level WARNING.

Level	Numeric value
CRITICAL	50
ERROR	40
WARNING	30
INFO	20
DEBUG	10
NOTSET	0
