Tool/software: Code Composer Studio
Dear TI BLE-5 Support Engineers,
I am using 2 x LAUNCHXL-CC2640R2 , simplelink_cc2640r2_sdk_1_35_00_33 stack, and projects example available on the GitHub.
I tested the SPP (Central and Client) Projects, I noticed that the long range not enabled.
I need your help and your support to know :
Regards,
Haithem.
Hello.
I'm looking into the long-range mode (or 125kbps coded Tx mode) myself. I wanted to give this 'long range demo' a try, but could not find it in the example folders of the 1.35 nor 1.40 stack.
Also, the example code for simple-ble-peripheral includes some ifdefed-out code for enabling coded transmission.
bool SimpleBLEPeripheral_doSetPhy(uint8 index)
{
uint8_t gapRoleState;
uint16_t connectionHandle;
static uint8_t phy[] = {
HCI_PHY_1_MBPS, HCI_PHY_2_MBPS, HCI_PHY_1_MBPS | HCI_PHY_2_MBPS,
// Note: BLE_V50_FEATURES is always defined and long range phy (PHY_LR_CFG) is
// defined in build_config.opt
// To use the long range phy, HCI_PHY_CODED needs to be included
#if (BLE_V50_FEATURES & PHY_LR_CFG)
HCI_PHY_CODED, HCI_PHY_1_MBPS | HCI_PHY_2_MBPS | HCI_PHY_CODED,
#endif // PHY_LR_CFG
};
GAPRole_GetParameter(GAPROLE_STATE, &gapRoleState);
GAPRole_GetParameter(GAPROLE_CONNHANDLE, &connectionHandle);
// Set Phy Preference on the current connection. Apply the same value
// for RX and TX.
HCI_LE_SetPhyCmd(connectionHandle, 0, phy[index], phy[index], 0);
Display_print1(dispHandle, SBP_ROW_RESULT, 0, "PHY preference: %s",
TBM_GET_ACTION_DESC(&sbpMenuMain, index));
Display_clearLine(dispHandle, SBP_ROW_STATUS_1);
return true;
}
Should I simply rebuild the stack and app projects, with BLE_V50_FEATURES & PHY_LR_CFG defined? Is that enough to enable the 125 kbps coded Tx mode?
Thank you
