Hi Dialog,

    I'm developing an UART to BLE solution based on DSPS_6.150.4.50. Functions are OK, but the BLE signal is too week to pass through water. Is it possible to add a power amplifier(for example SKY66114-11) to DA14531's radio antenna? How can I check DA14531 radio Transmit/Receive status to switch Receive LNA mode/ Transmit low-power mode of the power amplifier?

I hope to receive your suggestions. Thanks.

Hi zyj,

Thanks for your question online and for your interest in our DA14531 solution.

Could I ask what is the preferable Tx power? DA14531 has a configurable Tx power from -19.5 dBm to +2.5 dBm.

Regarding the external PA, let me check this.

Thanks, PM_Dialog

Hi PM_Dialog,

I set the Tx power to +2.5 dBm, but the RSSI of signal passed through water was still weak. 

I'm trying to add the external PA SKY66114-11 to hardware solution.

Thanks.

Hi zyj,

We have taken this offline from the forum and someone from the Chinese Team will reach out to you directly.

Could you offer the Chinese Team's contact information(e.g. email/ telephone) ? Suggestions from Dialog are important to this solution of my company's product.

Thanks.

If not, please let me know.

Hi PM_Dialog,

Last week, a FAE engineer of the Chinese team had contacted me.

I purchased  DA14585 Range Extender for further development.

Thanks a lot.
