Hi, I have been attempting to establish a BLE connection between my Particle Monitor and another NRF52840 device. However, the following logs have occurred multiple times (sometimes after hours) before the connection could be successfully made: [app] INFO: Into Scan Result [app] INFO: MAC: 12:34:…

The HAL functions are part of Device OS, so enabling debugging is difficult, because by default it will not be flashed to the device when you build your firmware, and pre-built binaries (without your change) will be used by default. The easiest way to force a modified version to be used is to follo…

Thanks. I'm on 5.7.0.... Let's me try the new 5.8.0 firmware. When I use my phone to clone the nrf52840 device, my phone has the same characteristics, and the particle device connects fine. However, the issue only occurs when the nrf advertises itself, so I'm curious why that happens

The issue still happen on 5.8.0 firmware for the Edge

I tried the flash application for debug(local) but the log isn't giving me much info regarding why it dropped ble connection when trying to discover characteristic.

Was there a version of device OS where this worked fine? A problem that came up with recent device OS versions?

I began with version 5.7.0 and have not experimented with any versions older than 5.7.0. However, I recently tried version 5.8.0 but same issue happen. case NodeState::Scan: { //Log.info("SCan For device"); BLE.scan(scanResultCallback); break; } case NodeStat…

The Monitor One uses the Tracker SoM BLE chip antenna on the board and does not include a separate BLE antenna, but one could be added using the BLE U.FL connector. Seem like it's working better with using external antenna but sometimes still running same issue. Any thoughts would be appreciated!

Just to be sure - you did enable the external BLE antenna in software using BLE.selectAntenna() ; it's not automatic.

Hi, what deviceOS are you using? There was this issue on BLE on 5.7.0 that was resolved on 5.8.0.
