Resolved! WB55: Leaving the chip in the brick after loading the stack. Very important for everyone.

2 years ago it happened that the controller turned to brick. I corresponded with technical support for a long time and I was offered to send the controller to the factory or representative. But since the case was a single one, I did not take advantag...

The NUCELO-WL55JC2 433MHz transmission is greatly attenuated with LPO, but works at range with HPO. Is that a known issue?

In my testing, I programmed two NUCELO-WL55JC2's to communicate with one another. I found that I could only receive if the transmitter antenna was aligned and touching the receiving antenna.After further debugging, I traced the issue to the LPO.Using...

Aci_gap_set_discoverable() returns Command Disallowed after long period of execution (100+ connections, wakeups and advertisements)

I've been experiencing an issue where sporadically the aci_gap_set_discoverable fails to start due to a command disallowed error (similiar to this) on the STM32WB50.For context: the device goes into sleep mode and wakes-up 100+ times per day. In slee...

I'd like to use a STM32WL55 or B-L072Z-LRWAN1 as a 'beacon sniffer' and 'packet sniffer'.

I'm busy debugging the RF conditions around my LoRaWAN installation.I get a lot of variance in both RSSI and SNR (+-10dB/+-6dB) and am trying to find it's source.In the absence of an SDR and other equipment, is it possible to read and report RSSI an...
