@jmarcelino I am still in need of a way to use NB-IoT on fipy. Is there a way to achive it? As I can see others have the same problem as me, so can we have some update on the state of the matter?

@helalbr I used both. But after the devices had been authenticated by OTAA once, I copied the credentials from the TTN console into the ABP script. ABP starts faster.

@jcaron thank you, I am using an expansion board, but I will try it whit pysense.

@jmarcelino I'm getting the following error: Traceback (most recent call last): File "main.py", line 13, in <module> AttributeError: 'RTC' object has no attribute 'irq' MicroPython v1.8.6-849-83e2f7f on 2018-03-19; FiPy with ESP32 Type "help()" for more information.

@kevina Thank you for the heads up, unfortunately it seems an older pre-release version of the datasheet slipped into Mouser. We'll contact them to update it.

Hi @kevina Unfortunately Pycom doesn't/can't offer area specific coverage information. Officially the only supported setup is Verizon using Verizon Cat M1 SIM card.

@smbunn It's still a single step to change the LoRa region but now you can either fix it in firmware configuration, or use the region= parameter. I recommend always the region parameter going forward. The firmware method was added more so existing code without the region parameter wouldn't break.

Thanks @seb and @jmarcelino for testing purposes what is the cheapest way to setup an indoor gateway? @jmarcelino I've just added sigfox to home-assistant btw https://github.com/home-assistant/home-assistant/blob/dev/homeassistant/components/sensor/sigfox.py

Hi friends, You can not connect through FTP in FileZilla, then this answer for you. You can use FTP account to create your website'sFTP accounts. FTP allows you to manage your website's files in cpanel. To create an FTP account, you need to perform a simple task. Login to your domain cpanel account. Find out File section and in that FTP accounts. Click over there to create FTP account with Linux. After entering you first need to set FTP login name and choose the particular domain name for FTP account if you have another domain or subdomain. Generate strong password with the help of Password Generator and set password. While setting password strength of password can be measure through the “strength”. You can choose different-different directories for different-different domains or subdomains. You can create separate FTP account for any of the directory in cPanel. You can choose FTP account quota with specific figure or simple choose it unlimited. Lastly click on Create FTP account. And your FTP account created successfully. To access this newly created FTP account in filezilla. Simply click on the configure FTP client and you will get the username and the password you inserted at the time of creating FTP account. Open filezilla and enter credentials and access your FTP account in filezilla. Follow this steps and click the following link to get more information. Create FTP & FileZilla Access Thank You.

@kevina Sorry, you didn't say in your original post you didn't have the module + pysense. The output is as follows: >>> i2c.scan() [8, 30, 41, 64, 96] You can also look through the libraries here to figure out the addresses: https://github.com/pycom/pycom-libraries/tree/master/pysense/lib 8 = PIC microcontroller (UART + deepsleep) 30 = LIS2HH12 41 = LTR329ALS01 64 = SI7006A20 96 = MPL3115A2

@jcaron on post page it is in the right top corner (compose?) but no one look at it ;-)

@mj Any single cell lipo with a JST-PH connector. Be careful of the polarity of the connector, there doesn't seem to be a standard so you may need to swap the connector wires around before plugging it in.

@nicobijl Interesting use case, though you'll be faced with reflections and multipath which may give you false results, depending on the exact layout (and most importantly, distances). Also, you should check the gain of your antenna in various directions, it's not because it's "concentrated" in some directions that it doesn't receive anything in others. Note also that if you do anything that transmits (active scanning, which I believe is the default now?), using a directional antenna means more gain, which may bring you above the allowed TX power threshold (depends on your region). Conversely, at short distances the high gain main saturate the receiver. Finally, one would need to check the exact radiation pattern, but I'm not sure 4 such antennas would be enough to cover 360°, they have a relatively narrow aperture. Let us know what you find out!

@robert-hh It quite often happen when 2 devices are active.
