CC1310: the sensor call ApiMac_mcpsDataReq to send out data but return error number 0x1a sometimes

Part Number: CC1310

Hello TI experts,

we are using SDK as bellow:

---linux stack gatew4ay sdk :ti154stack_linux_x64_2_05

---simplelink:simplelink_cc13x0_sdk_2_10

the basic configuration like this:

-- non-beacon mode

-- without mac security

-- no frequency hopping.

test case and test step as following:

1. try to associate the sensor with collector.

2. after association confirmed in sensor side, we will send BIND CMD(application related) to collector.

we found the send failed with the error number 0x1a, the probability is about 10%.

from the code, this error defined like this:

/*!
The operation could not be completed because no
memory resources were available
*/
ApiMac_status_noResources = 0x1A

could you please help on this issue and give ways to save more memory?

thanks

Do you keep sending packages very fast? If so, try to slow down sending speed.

thanks Chen,

we already add gap to 300ms between two sendSensorMessage() calls with the same size data, but the second sending almost always fails .

How many bytes you send in a single packet?

we send 158 bytes data previously without problem,
after upgrade to the latest sdk,
no we reduced the data packet size to 53 bytes but still fails ..

Hi,

To save a bit of memory, one of the things you can do is reduce the value of "MAC_MAX_FRAME_SIZE" to a value that makes more sense for your application. reducing this value will save some memory when trying to allocate memory for RX packets.

Please make sure that you are not allocating too much memory in your application also double check that you don't have large statically allocated data that you might not be using or might not be necessary since this will reduce the size of your heap when the heap is created.
