mesh long range

[richardjallen]

I am currently trying to extend the range of the bluetooth mesh application. The infocentre infers that the function:

 typedef struct
  120 {
  121     radio_tx_power_t tx_power;       
  122     uint8_t          payload_maxlen; 
  123     radio_mode_t     radio_mode;     
  124 } radio_config_t;

should be used to increase the range by reducing the radio_mode_t:

typedef enum
   74 {
   75     RADIO_MODE_NRF_1MBIT,   
   76     RADIO_MODE_NRF_2MBIT,   
   77     RADIO_MODE_NRF_250KBIT, 
   78     RADIO_MODE_BLE_1MBIT,   
   79 #ifdef NRF52_SERIES
   80     RADIO_MODE_BLE_2MBIT,   
   81     RADIO_MODE_NRF_62K5BIT, 
   82 #endif
   83     RADIO_MODE_END
   84 } radio_mode_t;

however, the radio_modes_t struct is not explained (both of these are found in radio_config.h).

I am currently using a few nrf52840 pdk's, which mode will give the most range for these boards? And is there a place I can find more information on this topic?

Thanks, Richard

Is there a plan to implement longer range (500kbps or 125kbit Radio modes) in the Bluetooth mesh?

If you have not done so earlier you can switch to the long range PHY for the BTLE Mesh, look at this case for specifics.

Would long-range device be able to read beacons from "short-range" devices?
