We have noticed an increase of power consumption with the BLE sleep mode enabled.
After the last advertizing peek, an increase of current occur after 2,5 seconds going from 20nA to 200nA.
With an advertizing period lower than 2,5 seconds, everything is fine. When the advertizing period is higher than 2,5 seconds, we observe the current increase for the remaining time until the next advertizing message. If i configure an advertizing period of 3 seconds, the excess of current consumption last for 500ms.
My objective is to reduce power consumption by disabling advertizing period for some time, but i don’t gain anything with this behaviour. If the advertizing is disabled for 30 seconds, i ll have a low current of 20nA only the first 2,5 seconds then 200nA during 27,5 seconds!
The RSL10 is in BLE sleep mode during that time, has OnSemi any explanations related to this behaviour
in regard of the BLE stack?
