Compiler error problem of "nrf_esb_rf_channel_get()" in SDK 11.0.0

[chianglin]

Hi,

I have a compile problem in esb_ptx of SDK 11.0.0.

When I add a esb command "nrf_esb_rf_channel_get()" in nRF5_SDK_11.0.0_89a8197\examples\proprietary_rf\esb_ptx\main.c, like following source code

nrf_esb_rf_channel_get(&rfChannel);
NRF_LOG("rd-Channel: %d\r\n", rfChannel);

It will cause one error message when compiler. Please reference following message.

linking...
.\_build\nrf51422_xxac.axf: Error: L6218E: Undefined symbol nrf_esb_rf_channel_get (referred from main.o).
Not enough information to list image symbols.

Would you please tell me how to fix this problem?

Thank you,

Chianglin

Hi,

If my 51822 version is QFAAG0, what is the most update SDK that I can use, and it ESB function is all ok?

Thank you,

Hi,

The latest SDK version that support the nRF51-series is SDK 12.3. You can download it from here.

Note that the bug is also found in SDK 12.3, so as mentioned in the post I linked to, you need to change the function name from nrf_esb_rf_channel_get to nrf_esb_get_rf_channel in the nrf_esb.h headerfile.
