1. [RTLS Passive] AoA angle calculation is deviated in small angles (0-10 degrees)
2. [RTLS] Angle performance is not stable when antenna array 2 is used
3. [RTLS] Configuration of slot_duration=1 is not supported in AoA
4. [TOF] ToF Master/Slave may go out of sync when RSSI is below -60
[Workaround]: This workaround corrects the issue BLE_AGAMA-1411 (ToF Master/Slave may go out of sync when RSSI is below -60).
In your RTLS project, replace the files TOF.c/.h and tof_security.c/.h by the following ones:
TOF.c
TOF.h
tof_security.c
tof_security.h
5. TOF is not stable for connection interval greater than 1 second
6. [AOA] When using only two antennas, the following code modifications are required:
#define AOA_NUM_ANTENNAS 2 //3 //!< Number of antennas in antenna array
uint8_t antArray[AOA_NUM_ANTENNAS + 1] = {ANT2, ANT1, ANT_ARRAY}; AOA_initAntArray(antArray, AOA_NUM_ANTENNAS + 1);
const int16_t AoA_A1 = antA1Result->pairAngle[0] + antA1Result->channelOffset[antA1Result->ch]; const int16_t signalStrength_A1 = (antA1Result->signalStrength[0]);
7. When only the master and the slave devices are used, the GUI does not display the AOA properly. A workaround has been provided in this thread.
1. rtls_agent_cli has an issue where the incorrect AoA start request can be invoked via the websocket (e.g. when using RTLS_Monitor GUI)
The fix is to remove any references to _cc2640r2 flavors of commands. from ss_rtls.py. See the snippet below on which code should be removed
class AoaStartReq_cc2640r2(NpiRequest, SyncReq, FromAp): command = Commands.RTLS_CMD_AOA_ENABLE struct = Struct( "enable" / Int8ul, ) class AoaSetParamsReq_cc2640r2(NpiRequest, SyncReq, FromAp): command = Commands.RTLS_CMD_AOA_SET_PARAMS struct = Struct( "aoaRole" / Enum(Int8ul, AoaRole), "aoaResultMode" / Enum(Int8ul, AoaResultMode), "cteScanOvs" / Int8ul, "cteOffset" / Int8ul, "cteTime" / Int16ul, )
Also the following code should be removed from the bottom of the file:
@builder_class(AoaStartReq_cc2640r2) def aoa_start_cc2640r2(self, enable): pass @builder_class(AoaSetParamsReq_cc2640r2) def aoa_set_params_cc2640r2(self, aoaRole, aoaResultMode, cteScanOvs, cteOffset, cteTime): pass
2. All the readme.html are missing for rtls examples.
The original README.md files which are used to generate the html files are still in the folder, users can take a look at those files to get started.
3. rtls_master does not support sampling I/Q on AoA pakckets.
For convenience, a new binary can be found here, use this in place of the one in the SDK:
/cfs-file/__key/communityserver-discussions-components-files/538/rtls_5F00_agent_5F00_cli.exe
