Ant+ connection is too close

[burton.yin]

Development Information:
1. We use the development board PCA10040 provided by the distributor; 2, example:nRF5_SDK_14.2.0_17b948a\examples\ant\ant_plus\ant_bpwr\bpwr_tx;
3, the chip is 52832;
Problems:
1, with garmin EDGE 1000 connection, distance more than 2 meters is very open,;
2, set err_code = sd_ant_channel_radio_tx_power_set (m_ant_bpwr.channel_number, RADIO_TX_POWER_LVL_4, 0); After the distance can only be 3 meters, the distance is too close, can not be used;
3, the same hardware, Bluetooth connection distance of more than 10 meters

Hi,

Do you see this only using "Garmin EDGE 1000", or do you see this also using other ANT+ enabled devices with the PCA10040?

Do you have other Nordic ANT+ enabled products you can use with the "Garmin EDGE 1000" for comparison, as listed here:
https://www.thisisant.com/developer/components/ 

Is it the same if you do the test in a different room?

Best regards,
Kenneth

We only have "Garmin's EDGE 1000" here, and our development board "PCA10040" is officially provided, and on this development board, Bluetooth is working properly and the ant+ protocol stack is at "">https://www.thisisant.com" /developer/components/"Download;
"Garmin's EDGE 1000" is connected to a Garmin power meter, the work is ok, and it is in the same room

Not sure what is the best way to proceed here. We are not aware of any issues that may explain what you experience. It may be that you have received a Devkit that is not working as intended, it may be there is much interference in the environment, it may be that you need to try another SDK example for test, it may also be the Garmin EDGE 1000. To debug further you will need more hardware to test with and try to repeat the test in a different controlled (chamber) environment.

Best regards,
Kenneth
