External Antenna nrf52840 dk

[Paul M.]

Hi everyone,

I need to implement a coded Phy ble communication in a project and for that I wanted to use an nrf52840 dk. However, for it to be able to compete with the Aircable Host XR5 I would use instead, I need to attach an external antenna with a better gain.
I saw the J1 connector, but as I understood it that is not recommended for permanent use. Is it possible to just solder a wire to certain pins to connect an antenna?

Thanks and best regeards,

Paul

Hello Asbjørn,

thanks for the quick reply! I am currently evaluating the coded phy solution against the Aircable. The application is to communicate with an implanted bluetooth device. Since the body is moving I dont always have the same signal strength and a high-gain directional antenna also would not work. Coded phy would be an attractive solution, however I am losing the advantage of the high gain omnidirectional antenna I can use with the Aircable. If the solution using coded phy works out in the evaluation, I would design my own Board with an nrf52 or 53 chip on it to use coded phy with.

Best,

Paul

Hello Paul,

Good luck with the evaluation. The J1 connector can surely be used for your evaluations. Let us know if more questions should come up and we'll do our best to assist.

Best regards
