Port, board and/or hardware

RP2040 / Pico-W

MicroPython version

MicroPython v1.23.0-preview.116.g0432f7320 on 2024-02-12; Raspberry Pi Pico W with RP2040

Reproduction

This fault occurs when setting up a Bluetooth LE peripheral on a Pico-W. Three services are defined and added to the server configuration using BLE.gatts_register_services(). I've attached a code module to demonstrate the problem

BLE-OSError22.zip

Expected behaviour

The expected return from BLE.gatts_register_services() should be similar to that returned on an Arduino RP2040 Nano Connect using MicroPython v1.22.1 on 2024-01-05. E.g

((21, 24, 26), (29, 32, 34, 37), (41, 44, 46, 49))

Writes to values using these handles work as expected.

Observed behaviour

The returned set of handles from BLE.gatts_register_services() contains duplicates e.g.

((9, 12, 14), (17, 20, 22, 25), (27, 28, 28, 28))

Writing a value to handle 17 works OK. Writing a value to handle 27 causes Error 22.

Additional Information

The ESP32 port appears OK too.

No response

Observed behaviour

Traceback (most recent call last):

Additional Information

I've looked for a solution to a similar problem, but it doesn't help me.
I tried "micropython.alloc_emergency_exception_buf(100)" by ChatGPT, but it didn't work.
