nRF52840 Development Kit standalone Long Range & Porting Code from nRF52832

gos

Hello,

I started off with two nRF52832 Dev Kits, and have customized the UART Central - Peripheral example to send an array data from Peripheral to Central (no uart simulation).

However, I have realized that since I will use this in an Industrial Environment (measurements on Production of Precast Concrete Slabs), I will need the Long Range capabilities of the nRF52840.

Questions:

I need to perform long time tests of several Central - Peripheral pairs in a real Production environment before producing final PCBs.This means I will need to run for extended periods on a 3.6 V 2.2 Ah battery.

If I have understood the docs for the nRF52832 Dev Kit right SW6 (nrf only) can be switched to supply power to only the nRF52840 Chip.
Q1: Is this correct?
Q2: Will I still have access to the IO ports on the Header Pins?

Q3: Is the UART Central / Peripheral example (for the 52840 with SD 140) also available in "Long Range" mode, or do I have to make changes to enable Long Range?
Q4: What , if any, changes needs to be done to the UART Central / Peripheral example to enable Long Range?

Q5: Is there any Breakout Boards for the nRF52840 (like the Sparkfun Breakout Board for the nRF52832 )?

I advance thanks for tips and help!

    Hi Geir,

    It is a bit confusing when you mention nrf52832 dev kits and talk about long range which is only available on nRF52840. 

    From here on, I assume that you meant to use nRF52840.

    1) There is a thread on this which you can find here on how to power the nrf chip only on the DK.

    2) Yes

    3) You need to make few changes to enable long range mode and that NUS (ble uart) examples do not use this mode. The changes should not be very big, it is just to configure the device to be able to advertise/scan and connect in long range mode.

    4) We added long range to ATT MTU example in the blogpost mentioned here. If you download this zip file and compare this ATT_MTU example with the non edited SDK example, then you will see exactly those changes that you need to change the PHY to long range. Unfortunately we do not have any other example to demonstrate this feature apart from this.

    5) Yes, we have a USB dongle which might suit your need, or are you looking for something different?
