@robert-hh said in no can connect to vodafone spain NB-IOT with FIPY: The second number is the bit error rate (ber), whic is not know beforehand. So it means now the device detects is a proper signal. then. then, now I understand that it had a good signal, but the fipy was trying to attach herself all night, and she did not succeed. it's just waiting, or we should give it the command to attach repeatedly ... On the other hand, I'll check the commands you indicate

@protean Hi, when you click on "get location button", Device scans the wifi networks around and sends the result to Pybytes. Pybytes is using Google location API to figure out and the location.

@rcolistete thank you for the pointer I have tried and no problems so far I'll give it a couple of days before sending it to the wild :)

Hello, in this link they answer quickly to all the doubts. Sigfox Ask Regards,

@Paul-Thornton What is the answer to his question though? I too am very confused by the documentation for the Fipy and expansion boards. There is conflicting or outdated information regarding the expansion board v2.0 and v3.0. Often I don't know which is being referred to, and worse, Pycom's channel resellers like Mouser, Digikey, etc. often mix them up.

@wghirakawa The code seems to be ok. I don't have access to Cat M1 network (only NB-IoT available here) so I cannot test with the same Sequans firmware. Are you able to perform communication on the same APN and with the same SIM using different hardware? @iwahdan could you please take a look?

@robert-hh said in Fipy läuft nicht richtig ohne Atom: Achtung: Niemals eine Eingangsspannung an 3.3V anlegen. Das ist ein Ausgang. Hatte ich leider schon mal gemacht!. Hatte aber nicht mein vorheriges Problem verursacht das war ja schon von Anfang an so. Ich wünsche dir noch einen schönen Sonntag.

@combaindeft It's the same situation like with NB-IoT network of Slovak Telekom which I am using. It would help if it could be possible to set IP address of DNS server manually but I am not aware of such command. Another option is to implement DNS client directly in MicroPython.

@nada-ali talk to each other over what network? The answers may be very different depending on context...

@robert-hh I thought so. Thanks.

@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

@dommei That's means: "not registered, MT is not currently searching an operator to register to". At my device, it toggles between 2,0 and 2,2. The response you need is 2,1 or 2,5.
