Advertisement interval > 4 seconds cause problems.
我使用延长睡眠国防部e and modified the advertisement interval. Setting intv_min and intv_max up to 6400 everything works as expected. An advertisement package ever 4 seconds.
But if I set the interval to 8000 (and higher) instead of every 5 seconds, I got an advertisement package every 10 seconds. Every second package got dropped. From the current consumption I see how the BLE is switched on, but after 500us it gets switched off. After 5 seconds all 3 packages got send perfectly.
No clue whats wrong.
Thanks and regards
