BT Test Tx Sweep

[Guillaume Valles]

Hi,

When I start the TX sweep test with all 80 channels I get only 10 channels used by the RF. Also power strength of the channels is modulated. cf. attached frequency analyzer screenshot. Why are channels not used? Is there any limitation?

void radio_tx_sweep_start(uint8_t txpower, uint8_t mode, uint8_t channel_start, uint8_t channel_end, uint8_t delayms)

Hi,

I started the radio_tx_sweep_start test with the following parameters: tx_power=+4dBm mode=2Mb/s(data rate) start_channel=0 stop_channel=80 delay_ms=200 (ms) This for sweeping all channels and setting my spectrum analyzer with a sweep time of 100ms. I expected some 80 spectrums one for each BTLE channel. Instead I get only a few channels with a spectrum I do not understand. And each spectrum should last the delayms. Could you please explain how this test work? What test would you suggest to get a simple spectrum on the analyzer? I will try to launch this test with 1 or 2 channels today to get a simple spectrum.

Regards, Guillaume
