LAUNCHXL-CC1310: Simple Link TI 15.4 Stack Long range mode Problem

Hi ,

I am working on collector and sensor example from C:\ti\simplelink_cc13x0_sdk_2_40_00_20\examples\rtos\CC1310_LAUNCHXL\ti154stack

Out of box everyting is working as expected .

But when i try long range mode by configuring CONFIG_PHY_ID to (APIMAC_GENERIC_US_LRM_915_PHY_129) , i noticed

Sensor to Collector communication is working fine , i.e collector is able to receive the pkts

But Sensor board is not recieving any packet from collector . .

what may be the problem ? Any thing should be configured apart from CONFIG_PHY_ID . .

Using collector and sensor example ,with the default setting everything is working fine .

( FYI : C:\ti\simplelink_cc13x0_sdk_2_40_00_20\examples\rtos\CC1310_LAUNCHXL\ti154stack)

have you tried using the sniffer (www.ti.com/.../PACKET-SNIFFER-2) to see the packets over the air?

Also, one of the configurations that help when using LRM mode is to set the following macros as follows
/*! Min BE - Minimum Backoff Exponent */
#define CONFIG_MIN_BE 5
/*! Max BE - Maximum Backoff Exponent */
#define CONFIG_MAX_BE 8

Thanks for your suggestion .

Actually it was CONFIG_POLLING_INTERVAL , which is set as 60000 in LRM mode . .

I have changeg to 6000 and Now i able to recieve data .
