Does BLE have lower current consumption than ESB?https://devzone.nordicsemi.com/f/nordic-q-a/10436/does-ble-have-lower-current-consumption-than-esbI need to setup a nRF51 dongle as a transmitter and a nRF51 beacon as a receiver. The transmitter will send a byte every 7.8 ms (128 times per second). I am wondering whether to use ESB or BLE to minimise the current consumption.

If it had been the other way around, ESB would be a better choice.</p> <p>I calculated a current consumption of about 1.3mA with the parameters you gave me.</p> <p>Note: The connection interval (minimum time between sending packets) in BLE is set in units of 1.25ms, so the closest transmit interval will be 7.5ms which is also the lowest you can get with BLE.</p><div style="clear:both;"></div>
