I’m experiencing a significant delay when transmitting packets over Bluetooth on the Verdin AM62, which does not occur on a Toradex Apalis board with the same setup. Specifically, when sending 200 packets per second from the Verdin AM62, the receiving device takes 3 to 3.2 seconds to receive them all. However, when I run the same test on an Apalis board, the packets are received within exactly 1 second, as expected.
Testing Setup:
Modules:
Verdin AM62 with BlueZ version 5.6 (experiencing delay)
Apalis board (no delay, 1-second packet receipt)
Device and Testing Tool:
Using the nRF Connect app to test packet reception and observe timing.
Both devices are configured to transmit 200 packets per second over Bluetooth.
Configuration Details:
We have created a /etc/bluetooth/main.conf file to specify Bluetooth profiles, including A2DP and other standard profiles.
The setup is identical for both Verdin AM62 and Apalis boards to ensure consistent test conditions.
Issue Observed:
On the Verdin AM62, the receiving device displays consistent delays of around 3–3.2 seconds for 200 packets.
On the Apalis module, the same 200 packets are received in exactly 1 second.

Based on the context provided, the Verdin AM62 is experiencing a significant delay in Bluetooth packet transmission compared to the Apalis board, despite having identical configurations. The issue seems to be related to the Verdin AM62’s Bluetooth stack or hardware, as the Apalis board does not exhibit the same delay under the same conditions.
To address this issue, you might consider the following steps:
Bluetooth Stack Investigation: Check if there are any known issues or updates available for the BlueZ version 5.6 that could affect performance on the Verdin AM62. Consider testing with a different version of BlueZ if possible.
Hardware Differences: Investigate any hardware differences between the Verdin AM62 and the Apalis board that could impact Bluetooth performance. This could include differences in Bluetooth chipsets or antenna configurations.
Configuration Review: Double-check the /etc/bluetooth/main.conf file and other related configuration files to ensure there are no discrepancies that might affect performance on the Verdin AM62.
Performance Profiling: Use profiling tools to analyze the Bluetooth stack’s performance on the Verdin AM62 to identify any bottlenecks or inefficiencies.
Consult Toradex Support: If the issue persists, consider reaching out to Toradex support for further assistance, as they may have additional insights or solutions specific to the Verdin AM62.
