current consumption on ANT and BLE

[Ma Shuyu]

Connection interval: 2 second;

Master clock 32kHz;

Slave clock 32kHz;

TX power: 0dBm;

Slave device postback Master device's broadcast message every 6 second.

Master device send noting just keep connection that is only send no payload broadcast message every two second.

My question is how much current consumpts on Master device and Slave device when use ANT and how much current consumpts on Master device and Slave device when use BLE

[Stefan Birnir Sverrisson]

Hi

I can estimate BLE current consumption for you for the nRF51 device if you provide the parameters specified in the BLE current consumption guide, both for master and slave. For ANT, the current consumption should be very similar.

If you decide to go for our latest nRF52 chip, then the current consumption is about 50% compared to nRF51

You may use the Power Estimator on the ANT Website to estimate the power consumption for ANT, though it does not yet support the nRF52.

thank you,I visit the Power Estimator website link,and get the current comsumption for my design.I have a question wheter the thansmit channal reverse data can lower than 0.5HZ,such as 0.25HZ.And do you have an agent in china,and which company is your agent in china.

[Harrison Chin]

0.5 Hz is presently the slowest you may transmit, although if you require lower transmit power then that, your alternatives include transmitting on an on-demand basis (using asynchronous TX mode) to an ANT continuous scanning node, or using a transmit-only channel which disables ANT Coexistence and bi-directional communication.

There is a Nordic distributor in Shenzhen which you may be able to contact called Xuntong Technology (http://xuntong.en.china.cn/).

thank you very much
