Firmware release 1.1.0.b1

[perfeco]

This release supports LoRa transmission.
Release 1.1.1.b1 crashes and reboots a few seconds after a LoRa transmission.
Tested on LORA (MAC) mode.

@perfeco is that with the 868 or the 915 MHz version? Can you provide a small piece of code that reproduces it? Thanks.

Cheers,
Daniel

Test code for LORA MAC TX:

import machine
from network import LoRa, WLAN
import socket
from time import sleep

wlan = WLAN(mode=WLAN.STA) # Switch off WLAN AP
lora = LoRa(mode=LoRa.LORA) # Switch on LoRa
s = socket.socket(socket.AF_LORA, socket.SOCK_RAW)
s.setblocking(False)
lora.power_mode(LoRa.ALWAYS_ON)
sleep(.1)
s.send(">>> ")

• Crashes on os.uname() == (sysname='LoPy', nodename='LoPy', release='1.1.1.b1', version='v1.8.6-281-g75e2452 on 2017-01-03', machine='LoPy with ESP32')
• Works on os.uname() == (sysname='LoPy', nodename='LoPy', release='1.0.1.b1', version='v1.8.6-264-gadacebe on 2016-12-22', machine='LoPy with ESP32')

How do I check which frequency LoRa is using?

[perfeco]

Tested with lora.frequency() == 868000000

@perfeco thanks. I can confirm the issue is there. It crashes a few seconds after sending. We are investigating it... Will report shortly.

It only happens in LoRA MAC mode, not in LoRaWAN.

Lowest current consumption so far: 106 mA during time.sleep().

Is machine.idle() a low-power mode where all CPUs are supposed to be idle and execution stopped until next IRQ?

[perfeco]

It only happens in LoRA MAC mode, not in LoRaWAN.

Can a LoPy be LoRaWAN gateway to a LoPy device?

@perfeco said in Firmware release 1.1.0.b1:

It only happens in LoRA MAC mode, not in LoRaWAN.

Can a LoPy be LoRaWAN gateway to a LoPy device?

No, due to hardware. LoPy is a device with SX127x while a LoRaWAN GW requires SX130x chipset.

@bmarkus Thanks for promt answers!

@the_ned bump

Need that too.

@bmarkus It can be a LoRaWAN nano gateway listening to one channel at a time. Be mindful that this is not LoRaWAN compliant but is very useful in certain conditions. We will release the full firmware with this functionality early Feb.
