Downlink from ubidots to The things network

Hello! We are doing a school project where we use a pycom-unit to send signals once/twice a day to ubidots through TTN.
But we can’t get downlink to work, does anyone have a good guide for this? All we get is “failed event, something with webbhooks
Basically our unit needs acknowledge that TTN/Ubidots has recieved the data from the pycom, so the pycom can go back to sleepmode(low power where the network is disconnected).

All help appriciated, thanks!

Please refer to this help article.

All the best

Thank you, We’ve tried this but without result… So we are doing something wrong even tho the guide is really well done. Will try go through this guide again, maybe we missed something
