Re: Iphone & BLE disconnects

Just tried something that seemed to have a positive effect (for me and my iPhone!):
This is one of my lesser-used old dev boards, and it has had a previous version of ESP-IDF deployed to it.
I had been using 'make flash' and seeing the same issue above, but I tried a `make erase_flash flash` just now, and that seems to have made it work again! I can't say what exactly happened, but it might have something to do with initial RF calibration.
It seems a bit scary to me that IDF upgrades (e.g. OTA) might break radio functionality if/when a new calibration is required (it should be detected/initiated by the upgrade process, I should think).
