Resolved! What's the maximum ATT-MTU and minimum connection interval of WB55 with BLE 5.2?
I'm planning to use 2052 bytes per packet (ATT-MTU-2052) and I want to know if it is possible. So. here is a question.What's the maximum ATT-MTU and minimum connection interval of WB55 with BLE 5.2?
Resolved! It looks like ST LINK sleep support broke on IAR EWARM v9.20.4
Has anyone else seen this?I have never seen such a problem in years of debugging with EWARM and STM32's through sleep modes: using source and project files that debug fine with EWARM 9.20.2, now with 9.20.4, the IAR IDE is hung on the ST LINK driver ...
STM32WB5MMG module, are there a version with MHF4 or IPEX1 antenna connector planned?
Hi,I wanted to ask if there is a variant of the STM32WB5MMG planned in the near future (~1 year) with a MHF4/IPEX1 antenna connector instead of the integrated one.There are some cases where it is useful to move the antenna (for instance because of a ...
