MPSL ASSERT: 1, 1310

[HauJohn]

I encountered the error MPSL ASSERT: 1, 1310 when establishing a BLE connection on my custom board, only happens when using an external 32 kHZ crystal oscillator (

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL). Could you provide information on what issue this error might be related to? 

I am using nRF Connect SDK v2.9.1. My custom board is based on the nRF54L15.

I just want to clearly understand what the parameter CONFIG_MPSL_HFCLK_LATENCY means. Is it the ramp-up time during packet transmission and reception as shown in this diagram?

If that’s the case, then increasing this parameter could reduce the transmission speed, right?

No, it's telling the software how far ahead of the BLE event that it should startup the HFCLK.
