Hi Chianglin

It's good to hear you figured out the cause, I will close this case then 🙂

Best regards

Hi Torbjørn,

Thank you for your answer.

I had found the reason -- It's hardware problem.

Thank you,

Chianglin

Hi Chianglin

I assume Andrew is currently unavailable, but I can confirm that you can use these two examples to test BLE communication between your two boards.

Please be aware that these examples use the physical UART on the nRF52 device to enter and receive UART information passed over the BLE link. This means you need to connect the UART interface of your modules to something.

On the nRF52832 DK this is handled automatically by the Segger chip on the DK, which sets up a virtual comport over the USB connection to the PC.

Best regards
Torbjørn

Hi awneil,

So, I can use ".\nRF5_SDK_15.3.0_59ac345\examples\ble_central\ble_app_uart_c" for Central and use ".\nRF5_SDK_15.3.0_59ac345\examples\ble_peripheral\ble_app_uart" for peripheral?

Can I use '.\ble_app_uart_c\pca10040\s132“ and ".\ble_app_uart\pca10040\s132" to test?

Thank you,

Chianglin

I'd suggest the Nordic UART (NUS) examples - both Central & Peripheral are provided in the SDK.

Hi awneil,

If I want use BLE communication between two of my modules, could you please tell me which softdevice and BLE application can use?

Thank you,

Chianglin

You're not comparing like with like there!

What happens if you use BLE communication between two of your modules?

Or if you compare BLE communication between your module & a devkit to ESB communication between your module & a devkit ...

Hi Torbjørn,

Do you have any comment about this problem?

In previous mail, If I use the same module but use BLE stack, it can communicate success when the distance between android phone and module is more than 5 meter.

I also test the communicate distance by "esb_low_power_pxx" and "esb_pxx" program. The max distance is about 50cm.

How can I fix this problem.

Thank you,

Chianglin

Hi Torbjørn,

I had check my "custom board" again. If I use BLE mode and communicate with android phone, he communicate distance is more then 5 meters, but if I use ESB protocol, the communicate distance is less then 1 meter.

Following image is my ESB setting, and I had modify the value of "NRF_ESB_MAX_PAYLOAD_LENGTH" to 240.

Thank you,

Chianglin

Hi Torbjørn,

It is a custom board. I had use this custom board to test BLE function, it can communicate well even in 2 meters.

Could you please give me some idea about "extend the communicate distance of ESB"?

Thank you,

Hi Ives

What kind of hardware are you using for this test?

Is it a Nordic devkit, or a custom board?

Best regards
