Hi guys,
First post here. Be gentle.
I am working with particle Argon SDK 3.3.0. I have read several other threads. When I connect to my BLE peripheral device from Argon acting as central, there is no way to change the MTU size.
The error is
0000533316 [hal.ble] TRACE: sd_ble_gattc_exchange_mtu_request() failed: 17
I can work with MTU sizes of more than 200 bytes with the same BLE peripheral when my central device is my laptop or a raspberry pi so the only one I cannot make it work is Argon.
Any hint how to solve this? Also tried calling functions from the HAL driver, no luck.
Maybe this is solved in SDK v4.0.0beta which I just saw available?
Please let me know your thoughts and have a nice day.
