Based on hobbya’s suggestion, I measured the current when the peripheral only advertises.
- Average current for data transmission every 10 seconds
The method the peripheral only advertise could reduce the current to 115uA, which would be a great benefit for data transmission. This can be very effective for transmitting a small amount of data. - Sleep period current
The average current during the sleep period is less than 5 uA, which is comparable to the DeepSleep mode.
