Can I use nRF52840 Evaluation Board to Verify Packet Error Rate and RSSI of other PCBA having Bluetooth LE?

Hi Guys, I Searched many forums but could not get a clear idea about using this nRF52840 evaluation board for Bluetooth LE Packet Error rate and RSSI testing of other PCBA. My Condition is I need to test bluetooth functionality of MAX32666 SOIC assembeled in custom PCBA Can i test this using our nRF52840 evaluation Board. Any suggestions are very helpful

nRF52840 pin reset behaviour

The datasheet appears to say that a pin_reset does not completely reset the chip: in particular it does not reset the SWJ-DP interface which, I believe, in some circumstances leaves the debugger running and causes excessive current. This is referred to in this case: https://devzone.nordicsemi.com/f/nordic-q-a/73447/the-nrf52832-did-not-halt-after-hardware-reset-pin-reset/303788 and this case: https://devzone.nordicsemi.com/f/nordic-q-a/77812/nrf52840-current-consumption-increases-by-more-than-1ma-after-pin-reset-with-nrfjprog--p I have two questions: 1) Is the table above correct because when we issue a soft reset from nrfjprog we do not get the extra 1ma which implies that SWJ-DP is being reset 2) Is it possible for the firmware to determine the state of SWJ-DP and, if necessary, disable it Thank you, Martin

Is the nRF52840 QFAA QFN48 package chip available?

Hello, This question has been asked - but that was awhile ago - some could say in an almost different landscape than what's going on today - so, please don't answer this was answered 4 years ago - keep in mind 4 years ago was 2017 - how hard was it to find components then? Is the nRF52840 QFAA QFN48 package chip available? Thanks, johnwest

NRF 5340 DK antenna array

Hi all, May I know is the antenna array a built in in 5340 DK or not? According to https://developer.nordicsemi.com/nRF_Connect_SDK/doc/latest/nrf/samples/bluetooth/direction_finding_connectionless_rx/README.html, it shows that there is Nordic Semiconductor design 12 patch antenna matrix, but I can't find any information of that, is 5340 DK already has it? Thank you. Best regards, Marco

nRF24LE1G (OTP)

Question on an older chip: Can anyone tell me if FW originally written for the nRF24LE1E would be completely compatible with the nRF24LE1G? I have an opportunity to source the nRF24LE1G but I am worried there may be hidden implications. PS. I am aware there are differences when flashing the chip.

How to calculate Time of Fly between two nrf52832 device

Hi support team, I'm learning about distance calculation based on time of flight. I only have nrf52832DK here but i wanted to try. I'm looking for an example of getting the exact time when sending and receiving a message. I know that to measure very small time (0.033us/10m) need high precision directly working on the BLE registers and timer counter. Are there any similar examples? I found this example of sending advertise packet without softdevice, it's useful to mark the sending time. Many thanks
