Long range advertisement with nRF52840

Hello,

I have programmed Fanstel BC832 module with S132 and ble_app_blinky example successfully and I can see the advertisement of BC832 on nRF Connect app. The thing is that the range is approximately 50 m. My main target is to see the advertisement in long range. I learned that  BC832 (nRF52832) doesn't support long range coded PHY.

I know that I should use ble_app_blinky_c and ble_app_blinky since nRF52840 can do both central and peripheral. My questions are:

1. Let's say I have 2 modules (for example 2 Fanstel BT840s) that are based on nRF52840 IC. Is it possible that I can create such a transmitter-receiver system in long range with these two modules ? I mean I will program one BT840 with ble_app_blinky_c  as a receiver and program the other BT840 with ble_app_blinky as a transmitter. If it is possible, how can I monitor this transmitting-receiving operation between two modules ? I have a nRF52840 DK and nRF Connect 3.3.0.

2. I was told that  the default blinky example is running 1M PHY. I want to use 125 kbp long distance with a module that is based on nRF52840 IC. How can I change PHY for long ranges. 

3. I have a BWG840F gateway which includes BT840 module. I was told that I can use 1M PHY for BWG840F and BC832. I need to set up the same PHY for these modules. How can I set PHY ?

4. Do you suggest another SDK example for a module to advertise or should I continue with ble_app_blinky example ?

5. There are BLE 5.1 modules. Can I use nRF52840 DK for BLE 5.1 applications ?

Thank you,

Best Regards

  • Hi

    The example in the blog does use buttons on the DK to switch between advertising modes, etc. so you'll have to add some buttons to the module, or edit the application to work around this in some way. Other than that, there shouldn't be any problems running the project on the blog as far as I know.

    Best regards,
