I am going to buy this module soon.
I think i can make great projects with it

I am aiming to create a Shutter-remote with this. I'll have some Ethernet/Wifi based automation at home that controls the Shutters (can be triggered with RPCs).
- The Lore receiver is hooked up to my Ethernet so that it can trigger the Shutters packets.
- The Lora transmitter (remote) will be basically in DeepSleep until someone presses a button on it to wake it up and send the Command over Lora to the Receiver (both are sending receiving of course since i want to display if the message has been consumed).


Encryption, DeepSleep and Remote Power Optimization are object of further development once the basics work.

how to config a heltec in platform io?

Two questions :
1. I assume we need to upload the code on both devices. Didnt find a specific mention of it in the video.
2. While uploading I am getting an error in the code line Mcu.begin(HELTEC_BOARD, SLOW_CLK_TPYE);

Not used: C:\Program
exit status 1
'HELTEC_BOARD' was not declared in this scope

Appreciate if you can provide a solution.

About the projects the one I would like is to use Blynk together with Lora for monitoring remote tank levels. Please develop one.

Get 5 of them, Set them up to send a Distress signal from a key fob. Hide 3 of them in cans and spread them out to where you can send a signal from your fob to soda can 1 ( with esp32 with battery inside ) and make Can 1 relay/repeat the alert to can 2 which will relay it to can 3 and then finally to your last ESP modules Display!. This would be useful for my friend who is an undercover detective. If you put batteries in them they could scatter cans at a site to relay the data back and forth, and if an undercover detective was in trouble, then they could press a button on the keyfob on their keychain, and that would trigger a message for you to repeat through the LORA eps32's scattered between you and them for you to get out of the Van and come save them ESP Display
