Firmware release 1.1.0.b1

[stevie]

@mohpor, actually I am not angry with the Pycom guys. I think they are doing a great job. They are developing the firmware farther at a steady pace. While they may be behind their initial schedule (or our expectations of the schedule) this is in big parts due to the fact that they are on the leading edge of the ESP32 users. Others playing around with the ESP32 are also delayed by the late delivery of the BLE features. If the ESP32 manufacturers don't deliver certain features, the Pycom guys can hardly deliver them either. All in all the WiPy and LoPy are great modules and I am sure they will improve further with time. As it is now, the best strategy would be to accept the development status as it is and just wait and help prioritizing things.

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.

Cheers,
Daniel

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!

[maku]

@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.
