Certifications needed for ESB

[lgs-wtk]

Hello !

We are planning to use ESB to communicate in-between nRF52 devices in a public environment.
NB: our product only embeds the ESB stack - no bluetooth nor BLE tasked is performed by the nRF52 device.
- The product will be distributed worldwide.
- Wifi devices will be in proximity
- Bluetooth and BLE devices will be in proximity


Apart from the usual radio certification, is there any other certification that I must go through to ensure: 
1. Bluetooth compatibility (not perturbate / not be perturbated by)
2. BLE compatibility (not perturbate / not be perturbated by)
3. Wifi 2.4GHz compatibility (not perturbate / not be perturbated by)

Also, do you have any knowledge about some specific certification related to radio in a medical environment ?

Regards,

Laurent

 vHi

I asked internally if there are any ESB specific certifications, but there are only the "normal" RF regulatories like FCC and ETSI that are relevant. Worth noting that it is pretty straight forward as long as you don't plan on using a power amplifier (PA) for your antenna. If you plan on that there will be some more complications depending on what TX power you use etc. You should also not use the lowest and highest number channels allowed by ESB library, as they are outside the allowed band.

Regarding the ETSI certification, this is something that is certified for a finished products, and not for a module/SoC like the nRF52. We did do a ETSI certification for the nRF52 DK for ETSI EN 300 328 v2.1.1, and the only difference between V2.1.1 and V2.2.2 is the receiver blocking test. Attached is the ETSI test report for the DK for reference: 3301.359526-01 Nemko TRF ETSI EN 300 328 (nRF52-DK).pdf
