CC1310: the collector always chooses the lowest channel number

Part Number: CC1310

Hello friends,

we are using SDK as bellow:

---linux stack gatew4ay sdk :ti154stack_linux_x64_2_05

---simplelink:simplelink_cc13x0_sdk_2_10

our product works like this: one base station works as collector/coprocessor together with multiple sensors.

the default setting of the ti sdk uses only channel 0(config-channel-mask = 0 in collector.cfg),

as we changed one collector to use more channels(eg. 0 1 2 3),

we found this collector will still always choose channel 0 while there are several collectors already using channel 0 in the same office area.

seems the energy detect process can not detect the existing collectors operated in channel 0.

by the way, we already deleted the collector nv bin file to make sure energy detective process is done each time the collector started.

thanks,

Harbor

add some log info in findBestChannel @ cllc.c,
the energy result for each configured channel is always zero:

CHAN:0, energy=0, lastEnergy=0
CHAN:1, energy=0, lastEnergy=0
CHAN:2, energy=0, lastEnergy=0
CHAN:3, energy=0, lastEnergy=0

Hello Harbor,

Could you provide us with a little more information on your setup as far as what mode of operation you are using and what your full channel masks are in config.h?

Hi Matt,

thanks for your reply.

we are using 15.4 stack as following:
1. non-beacon mode
2. no frequency hopping
3. no mac security

in config.h, the default channel mask set as below:
#define CONFIG_CHANNEL_MASK_DEFAULT { 0x0F, 0x00, 0x00, 0x00, 0x00, 0x00, \
0x00, 0x00, 0x00, 0x00, 0x00, 0x00, \
0x00, 0x00, 0x00, 0x00, 0x00 }
but actually, the channel mask will re-assigned by getting the value from config file( collector.cfg), that's : 0 1 2 3.

thanks,

Harbor

Harbor,

Thank you for providing that additional information. I am going to pass this thread to the 15.4 Stack team who will better be able to further assist you. Thank you for your patience.

Best regards,

Matt

Hi Harbor,

We are currently looking into this issue. There seems to be a problem in the energy detect function in the libraries. I will let you know as soon as we have a solution.
