Hello, Im new in the hobby and just received yesterday 2 liligy t-beam T22_v1.0 20190612.
I played very much yesterday, with lot of headache as far as this latest design doesn’t comply much with even official lilygo github repo (Pull request waiting approval for the gps code there).
I would like to thank this forum as far as most of my working code found inspiration from multiple thread and hint from here.
Anyway, i did also a range test between a sender and a receiver. Im living in city, put the sender on my balcony (6m above street floor) and walked away around my building.
I approximatively reached 280m of range, before receiving stop with around -130 rssi.
All done with provided standard antenna (2dbi little one).
I would like to know which paths hardware and software, i can follow to extend this range.
Is using a higher gain antena such as 9dbi would improve the receiving range ?
Is there a way to ramp up the signal power on sender with software ?
Or are those devices just very limited and i should instead choose better one ?
