Hmmm, mine still not arrived. Ordered sept 28th…

price went up … I will test current consumption today… curious

Banggood… aaaaargh I’m not happy at all about their service.
I am still having a discussion about a product I ordered in August, and never received.
Yesterday they offered me a half what I paid, but the package was insured !

Dutch post nl didn’t deliver to me and for some idiot reason they said they sended it back to China.
Bangood stated ’ we’ll wait for the package , but me, as a customer, have no part in this, I want a FULL refund because a] package was insured and b] product was never delivered.

In short… hope your lock will arrive soon :wink:

Lesson learned… NEVER buy expensive equipment through Banggood … I have better experiences with E bay and Ali, much better service when something goes wrong !

*update- * must be reading here too… this morning ‘a manager’ offered a full refund for products I never received … after 3 months… thank you Banggood :sunglasses:

  • update 2 - oh yesss pompom
    bgrefund

reverse

Downlink is coming, don’t forget to reverse your IQ polarity so that the packet knows which way to go :wink:

lesson learned from the past, before wiring up everything, test individual ‘china’ modules.
here the 3231 RTC… is it still working ? and what about the coin cell voltage ect.

  1. A disadvantage of those black-yellow boards is that the 32Khz pin is not exposed.
  2. It is easy to make the board yourself (I prefer the smaller version of the DS3231 IC):

Just realised Neil @ Multitech had kindly shipped the LTE enabled version - MTCAP-L4E1…excellent!

Have got a couple of spare Data SIM’s here…

:thinking: guess what I will be doing tomorrow! :laughing:

Back to N.West later in the week and have the perfect site lined up to use it if I can arrange short notice access. Warrington Community should have a new GW online by the weekend…

that depends on the beer quantity … probably you only open the package :partying_face:

:rofl:

what’s your favorite RTC library ?

This one because I wrote it. It is not for Arduino… :man_shrugging:
Did you know the IC also has a temperature sensor in it. It is accurate enough to measure the temperature inside a project box.
