I thought I would write something about flashing firmware that everyone using elrs should know, and likely knows already, just in case someone doesn`t.
I am an elrs believer, after 12 months I remain convinced it outperforms other rc systems. An issue is that at regular intervals you may find yourself flashing rxs and tx modules, as there are frequent firmware upgrades to elrs and to edgetx. The wifi method is by far simpler than uart methods, but occasionally the wifi flash may fail with an error message such as 'not enough space'. And then the uart method can also occasionally fail, either because there is a mess on the memory of a rx from earlier efforts, or lack of space.
Fortunately a solution to this flashing problem is now at hand. ELRS Configurator v1.6.0 is now available, and elrs (since v 3.0.1) has a new features 'erase before flash' and 'force flash'.
Uart flashing is done is with a recovery dongle. John Hopke shows how its done with these 2 vids.
