NRF52840 + PHY_CODED + Android : Possible?

[marchefeu]

Hi,

I have a project that need to use a long range bluetooth communication with an Android smartphone or tablet

I use for test a tablet Lenovo Tab M8 TB8505F, NRF Connect says it was fully compatible with Bluetooth Low Energy: High speed and Long range is supported.

I have download project nRF5_SDK_15.2.0_mod.zip found in this post.

When I flash example ble_app_uart to DK board, the tablet doesn't detect it. But when I replace the BLE_GAP_PHY_CODED by BLE_GAP_PHY_1MBPS, project works fine.

init.config.ble_adv_primary_phy = BLE_GAP_PHY_1MBPS; // BLE_GAP_PHY_CODED;
init.config.ble_adv_secondary_phy = BLE_GAP_PHY_1MBPS; // BLE_GAP_PHY_CODED;

The range are better but not sufficient for my project.

is someone already realized a communication using PHY_CODED with a phone? However, what is wrong in this example?

Regards

Pascal

That's rather old - Current SDK version is 17.0.2

I work on version 17.0.2, program work but not with phy codec , tablet doesn't see it.

I have tested with SDK 15.2.0 or 17.0.2, Android device doesn't detect it. (or it's Nrf Connect that didn't see it...)
