So you are not seeing any improved range when increasing the output from the nRF RADIO from 0 dBm to +8 dBm? Could you provide the layout and schematics for your custom board here or in a private support ticket?

Currently we are trying to communicate between our custom made device with BT840X and a Fanstel Dongle BT840X. We are measuring range indoors now with few walls and also lots of space available for the devices to communicate with each other. The walls are only on one side between the devices and the right side is completely open.

Which device do you use to scan for the beacon? Is it another board with the same module, or are you using a different device? Is the module mounted on a custom board or a Fanstel DK? And where are you performing these measurements, indoors, or outdoors where you have a clear line of sight?

we were able to find the point where the device stops detecting for beacons at 8dBm at 40 meter .

How many meters range are you currently able to achieve, and how are you testing it?

We are using the BT840X device... It can go upto +21dBm.

What range are you currently achieving, and which device are you connecting with? The max. TX output power from the nRF RADIO is 8 dBm.

The nrfx_ppi.c was not properly added, so it was causing error. Now I can run it. But still the Device range has not been increased. Where can i set the TX power value for it. i was using BLE_TX_POWER as 8db before... But i cant increase the TX power again which will cause build error.

The linker error indicates that either the source file is missing or the preprocessor symbol has not been correctly set. Are you able to upload your project here so I can have a look?

HI,
Yes. I have enabled PPI in sdk_config.h file.

Both the nrfx_ppi.c and nrf_drv_ppi.c path has been added.

In code, we use "nrf_drv_ppi.h" and "nrfx_ppi.h" both as provided by Fanstel here.

Thank you.

Hi,

[quote user=""]I have already enabled the PPI,
#define NRFX_PPI_ENABLED 1
#define PPI_ENABLED 1[/quote]

Did you do this in your sdk_config.h header?

[quote user=""]The PPI file path has already been added.

Have you included both the /modules/nrfx/drivers/src/nrfx_ppi.c and the integration/nrfx/legacy/nrf_drv_ppi.c source file in your project?

Best regards,
