Python API release notes

This is very nice. For range testing i connect one device to my computer and run this script on it: import meshtastic import time interface = meshtastic.StreamInterface() while 1: str = time.strftime("%a, %H:%M:%S", time.gmtime()) interface.sendText(str) time.sleep(60) Each minute i get a notification on the device i bring on my walk. It is easy to see when you get out of range. So far i have only been 1 km out and had no missed messages.

Data bandwidth and latency

Hello, Today I tried to make some bandwidth test but no luck to get more than 1 message per second (: channel_settings { tx_power: 23 modem_config: Bw500Cr45Sf128 psk: "\327\241i\317\275\025y\301F\273t:\217\346@F\371\344\345\274\371D\336\007W\335\001i\336~Nc" name: "G1" } Pyhton script send 6 messages via first device import time import meshtastic interface = meshtastic.StreamInterface("COM6") for x in range(6): interface.sendText(str(x),'^all', False, False) and meshtastic…

Antenna improved range

My take of someone else post. Sorry, I forgot who. import meshtastic import time count = 0 interface = meshtastic.StreamInterface() while 1: str = time.strftime("%a, %H:%M:%S", time.localtime()) str =str + " \n\rDennis CQ CQ CQ " + ("\n\r message count = %d " %count) + “\n\r” interface.sendText(str) print(str) time.sleep(60) count += 1

Python API via USB

SInce bluetooth/Android are a bit of a struggle to get & remain connected, I though that I would give the Python API a try - but I have very little experience with Python so the comment ```# By default will try to find a meshtastic device, otherwise provide a device path like /dev/ttyUSB0 doesn’t help as I do not know how to change the path. Could anyone provide the alternative code to replace: *import meshtastic* *interface = meshtastic.StreamInterface()* *interface.sendText("hello mesh")* TT…

Python API setup issues

Making some progress… Messages are sometimes sent via the meshtastic executable but basit pythin has some issues: pi@pi-nas:~/meshtastic $ python3 experiment.py ERROR:root:Node not found for fromId ERROR:root:Error handling FromRadio, possibly corrupted? 40 Traceback (most recent call last): File "/home/pi/.local/lib/python3.7/site-packages/meshtastic/__init__.py", line 404, in __reader self._handleFromRadio(self._rxBuf[HEADER_LEN:]) File "/home/pi/.local/lib/python3.7/site-packages/me…

Meshtastic-Python current_packet_id help

I was interested in identifying any packets (sendText messages) that get lost so I would be able to resend them but I noticed that when querying meshtastic.StreamInterface().myInfo the current_packet_id never changes (even after sending a new packet). Is there another way to get the current id of the most recent packet sent or should I increment the packet id myself? This can be valided with the script below which will query myInfo then send a new packet in a loop. import meshtastic import tim…

Off-Grid Field Test: Meshtastic-Python, Heltec & custom board, hop connections

(filling in details in spare moments today ) … In case it’s useful, below is the Meshtastic-Python script I used on my ‘base station’ (a laptop with a Heltec Meshtastic widget plugged into a USB port) to listen for messages and reply to them, adding the SNR. I also added ‘hopLimit’, because at the time I thought it was a measure of the number of hops (not, as I now realize should have been obvious, a limit on the number of hops). import meshtastic import time from pubsub import…

self.currentPacketId = (self.currentPacketId + 1) & 0xffffffff TypeError: unsupported operand type(s) for +: 'NoneType' and 'int'

Hi, You can install the python client as described here The basic steps are $ pip3 install --upgrade meshtastic $ meshtastic --help $ meshtastic --seriallog stdout This works on Linux. I would assume the same goes for unix.

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, …
