Multiple stacks coexisting: Wirepas, BLE and LoRaWAN. Is it possible?

[Liz]

Hello,

I am trying to determine if it is possible to have those 3 stacks coexisting.

I have an iSP4520 chip, which includes an nRF52832 (BLE and Wirepas) and Semtech SX1262 (LoRaWAN).

I understand the physical limitation of having to share the same antenna between BLE and Wirepas.

I was wondering if there was a way that I could switch back and forth between the two options?

If so, what SDKs should I be looking into using?

Thank you for your help.

Hi again

I see, then you will need some kind of handshake between the Wirepas and nRF device (for example with GPIOs) to make sure that when one of them are using the antenna, the other will "stand down" and wait for its turn. Since the SDKs aren't compatible it will be necessary that you add a separate mechanism for this.

Unfortunately this isn't something we can help you with. When you have decided on the method to do so, we can help you implementing it on the nRF side, but you will be responsible for getting it to work with the Wirepas device in the end.

Best regards,

Simon
