I agree with @kersing that the Uno should have arrived with a bootloader pre-burned into it. If this is not the case you better tell the supplier so that they an fix the issue on their side.

Did a walk test today to see what the range was with my 2 gateways: very good results. However, i noticed that when the Uno couldn’t reach either gateway for about 10-15 minutes it powered off. The sketch was the “send 1 byte every 10 seconds” one. The power supply was a 20,000mAh powerbank. Pressin…

Was it the power bank shutting down ? A lot of them will do that when the current being used drops below a certain level for a particular time.

Good point! I know that Uno draws very little current so the powerbank may just be showing its normal behaviour under these conditions. I’ll need to do more testing, perhaps using the barrel connector.

I was viewing the TTN console on my phone, and also had the TTN Mapper app running at the same time. I can’t carry my laptop around the streets, unfortunately :grin: I could see from the counter field on the console that it was dropping transmissions when it was out of range.

I can only go by the fact that the TTN console was not showing any communications from the UNO, and when I believed it to be back in range, the counter number was not sequential.

Hi, I’d like to buy The Things Uno board. I’m from the Philippines…do you have any suggestion where I could buy it? I tried looking up to the RS website but it doesn’t ship to the Phils. Not sure about farnell though. But is there any other asian market which sells this board? Thanks in advance.
