Hi there,
I have set up an at3 sensrcore module to transmit frequency counter data on 2 channels, plus temperature and battery on a 3rd channel.
Frequency data channels are each mapped to an ant channel, temperature and battery share one channel with 50% channel time each. All channels are set up for 4 Hz tx rate.
After app. 12 hours of operation appearently the channels overlap. Using a slave in continuous scanning mode I get the following pattern:
# inside datagram, column 4, fa, fb, fc -- the master channel id
# fa, fb are the frequency data channels, fc temperature and battery
# appended the timestamp on arrival of the slave datagram
# appended the delta (time to next datagram)
I would expect 3 datagrams in a burst every app. 250 ms. However, some datagrams seem to get lost.
Attached a longer and better readable log as well as the senrcore setup file.
[ -- datagram received from slave -- ] -- timestamp [ms] -- delta between messages [ms]

As all channels are set to the same channel rate I don't understand this error.
# The at3 module was programmed using antware II and develpment board usb bridge.
# Before programming existing scripts were erased (successfully, according to antware).
# Once powered up, the data transmission seems to be OK.
# The master is powered from 2 AAA batteries in series (->3V).
# I have already tried several slave modules and radio-frequency setups.
Any ideas?
TIA + Best Regards,
Peter
