What is your problem?

Hi,

I'm currently working on connecting to a BLE device manufactured by the same person who provided me with the documentation. According to the doc, I should request an MTU >= 32. He shared me some logs where he's setting the MTU to 50 and the device is connecting accordingly, from a dedicated PC software he wrote.

Using the example app for this lib (and logs are in fact from the example app), anyway, I get the logs attached in the dedicated section. I have just cleared a bit some warning repeated multiple times (wrote once and then replaced by [..many of these]) and set the scan timeout to 3 seconds instead of 15.

It seems that it tries to request 50 (await connect(mtu: 50)), it goes back to 23 and then it gets disconnected with the very annoying 133 error that all of us hate so much! :)

If I don't specify any MTU, then it gets connected with MTU 23 (that should be the default MTU chosen by Android), but then I can't write some values to the characteristic because of data longer than expected (with the suggestion to ask for a greater MTU), also with allowLongWrite set to true.

Could you please provide me with some insights on how to effectively debug this issue with the individual responsible for the hardware?

Thank you sincerely, Lorenzo

unfortunately no good solution that I know of.

you can try googling for "ble sniffer", "ble packet capture", etc. If you can get access to the raw ble data thats ideal. I've never done that before though.

REMOTE_USER_TERMINATED_CONNECTION - this log means the BLE peripheral is very unhappy, and is deciding to end the connection
