@mraj By hardware or by software? By Software: if you have a communication defined, you can define a command which leads the Lopy to do execute machine.reset(). By Hardware: You need extra hardware, which depending on what you need either toggle the reset pin or power off/on the device. A separate small micro could do that, maybe even the PIC which now resides on the various expansion/ensor boards. There a subtle (unintended I guess) differences between machine.reset(), pulling the reset pin and power cycling the device.

@dan An empty string is returned in cases, when the LTE modem takes longer than 10 seconds to respond. Sending an empty AT command (lte.send_at_command('')) may show such a late resonse.

@nickb This is a standard AT command. the response tells: "scanning with unsolicited response enabled" (first 2), and "not registered, but MT is currently trying to attach or searching an operator to register to" (second 2) https://www.etsi.org/deliver/etsi_ts/127000_127099/127007/12.07.00_60/ts_127007v120700p.pdf or https://firebasestorage.googleapis.com/v0/b/gitbook-28427.appspot.com/o/assets%2F-LIL0iGdl11z7Jos_jpX%2F-LKN7scqKKkb6TqB3uYO%2F-LKN82sqi_sHewyinxC5%2Fmonarch_4g-ez_lr5110_atcommands_referencemanual_rev3_noconfidential (2).pdf?generation=1534782114581269&alt=media

@robert-hh Many thanks. :)

@tfgm Not directly with the FiPy. You can use a chip like INA219 to monitor the current & voltage at the wire getting in to the device, and then you can determine the mAh that have been consumed, and in combinations with the voltage also the energy. The timing resolution is not very good, mostly limited by the time you allow your code to measure. So you will miss small spikes & drops. For convenience, there are modules with that chip available. There are Python drivers from Adafruit and one here, tested on ESP32 and ESP8266: https://github.com/chrisb2/pyb_ina219 Both should be close to Pycom's python. The gap, if at all, should be in the I2C section.

@dan I understand that and get this error when I flash it, but I would also like it to link in Atom so I can build and run it right away without having to flash it.

@shp96 That does not seem correct. Your gateway is only listening on channels 48 to 55 and 70... Can you show logs of packets received with the associated channel?

@panda Thanks for the input. My first thought was Hologram due to lower cost to get started. Long term commitment to data plan is another issue which I am not sure of. At this point, I am going to be trying lots of different things to arrive at a configuration that works for me. In a perfect world (lots of time and money) I would try both with two different setups connecting to the same sensor network and using the same code. Since my world is far from perfect, I thought I would ask. Hearing your experience with Hologram helps... functionality is also high on the list, and it seems like it is working good for you.

Hi @grideagle, Thank you for reporting that, I've reported it to GitBook. The current workaround is to use the "copy" button it the top right corner of the code section.

Interesting. I have not tried only powering via USB. I have always connected a seperate 5V supply to replicate the exact arrangement for my end solution. You also need the extra current to make the radio components work correctly. Good find. Peter.
