Working on a remote sensor node setup where the BLE module needs to spend most of its time in deep sleep and only wake up to push a data burst every few minutes. The issue I'm running into is I'm not sure how long I should expect the reconnection handshake to take after the module wakes from sleep, especially at longer distances - say 5-15km range. At short range it's pretty snappy but I don't have a second site set up yet to actually test the longer distances and I don't want to spec out my power budget wrong before I do.
