[nRF52840-DK/Radio Test] RX does not respond correctly when typing CLI commands

[Lulu.C]

Hello Sirs,

I loop typing the same command program:

clear>tart_channel 02>output_power pos0dBm>start_tx_modulated_carrier>cancel

After repeating the same instruction program for 5~6 times, RX does not respond normally after typing "start_tx_modulated_carrier".

Any help would be appreciated.

Best Regards,

Lulu

[Susheel Nuguru]

This this the log from the unedited radio_test sample of ours or have you made some changes?

Need to replicate the setup to be able to debug this issue, can you help me by sharing your project, sdk version and chip revision to be able to get more context on the issue.

[Lulu.C]

Dear Susheel,

I am using the default radio_test sample without major modification to this program.

sdk version>17.1.0 nRF5 SDK

chip revision>nRF52840-DK (PCA10056)

radio_test.7z

log_asc _RadioTest_nRF52840-DK.7z

Thanks & Regards,

Lulu

[Susheel Nuguru]

Apologies for delayed answer. I could not verify this behavior yet, due to fewer experts working here in Norway due to summer holidays, I will verify your project and the behavior soon on 840 DK, thanks for the patience.

[Susheel Nuguru]

Sorry for late reply, I tested the radio_test example on the nrf52840 DK and the commands works as expected. I did not have the time to review your changes, but the radio hw and the example works as intended.
