Meshtastic

Handling FromRadio, possibly corrupted?

Hi,
I’m trying the example from https://meshtastic.github.io/Meshtastic-python/meshtastic/index.html#meshtastic.MeshInterface
import meshtastic
from pubsub import pub

def onReceive(packet): # called when a packet arrives
    print(f"Received: {packet}")

def onConnection(): # called when we (re)connect to the radio
    # defaults to broadcast, specify a destination ID if you wish
    interface.sendText("hello mesh")

pub.subscribe(onReceive, "meshtastic.receive")
pub.subscribe(onConnection, "meshtastic.connection.established")
# By default will try to find a meshtastic device, otherwise provide a device path like /dev/ttyUSB0
interface = meshtastic.StreamInterface()

I’m on Windows 10 with https://www.aliexpress.com/item/4001178678568.html

and I receive this error:

Oops - I think that example is a bit stale. I’ll fix. In the meantime:

if you change onConnection & onReceive to the following:

def onConnection(interface, topic):

def onReceive(packet, interface):

I think you’ll be okay. Can you try that?

Hi Thank you for your help:
Code

import meshtastic
from pubsub import pub

def onReceive(packet, interface): # called when a packet arrives
    print(f"Received: {packet}")

def onConnection(interface, topic): # called when we (re)connect to the radio
    # defaults to broadcast, specify a destination ID if you wish
    interface.sendText("hello mesh")

pub.subscribe(onReceive, "meshtastic.receive")
pub.subscribe(onConnection, "meshtastic.connection.established")
# By default will try to find a meshtastic device, otherwise provide a device path like /dev/ttyUSB0
interface = meshtastic.StreamInterface()

and I receive this error:

doh! my memory was wrong. onConnection prototype must be:

def onConnection(interface, topic=pub.AUTO_TOPIC)

(I forgot that pubsub requires a default value for extra parameters)

I works, thank you for your help:
Code

import meshtastic
from pubsub import pub

def onReceive(packet, interface): # called when a packet arrives
    print(f"Received: {packet}")

def onConnection(interface, topic=pub.AUTO_TOPIC): # called when we (re)connect to the radio
    # defaults to broadcast, specify a destination ID if you wish
    interface.sendText("hello mesh")

pub.subscribe(onReceive, "meshtastic.receive")
pub.subscribe(onConnection, "meshtastic.connection.established")
# By default will try to find a meshtastic device, otherwise provide a device path like /dev/ttyUSB0
interface = meshtastic.StreamInterface()

No:I receive nothing … from the second module (nothing is printed)

I Receive that after some minutes:
ERROR:root:Node not found for fromId
Received: {‘from’: 862621965, ‘to’: 4294967295, ‘decoded’: {‘position’: {}}, ‘id’: 1323205740, ‘rxSnr’: 11.5, ‘hopLimit’: 3, ‘fromId’: None, ‘toId’: ‘^all’}

I open a second Topic for the sender: I have error also

hmm - what version of the firmware is on the devices? (it is printed on the screen at power on, or you can run meshtastic --info to get it)

It is possible that I’ve accidentially made a non backward compatible change in the python lib and the firmware that ttgo is prepopulating is pretty old…

I upload the firmware today:
meshtastic --info
