LAUNCHXL-CC1352R1: After 'central' received connection parameter updates, 'GAP_UPDATE_LINK_PARAM_REQ_EVENT' didn't appear

Hi Katherine,

Is simple_central answering to that UPDATE with

GAP_UpdateLinkParamReqReply()?

https://software-dl.ti.com/simplelink/esd/simplelink_cc2640r2_sdk/4.20.00.04/exports/docs/blestack/ble_user_guide/doxygen/ble/html/group___g_a_p.html#gaed1b6299bfe3b0469e2baf53cba04fe1?

Hi Arthur,

This function, GAP_UpdateLinkParamReqReply(), is under case GAP_UPDATE_LINK_PARAM_REQ_EVENT:

But it didn't enter GAP_UPDATE_LINK_PARAM_REQ_EVENT, so how could I confirm whether there was an answer?

Regards,

Katherine

Hi Katherine,

1) Just to be clear: When you say the device never enters GAP_UPDATE_LINK_PARAM_REQ_EVENT, are you talking about the peripheral or central device?

2) It may help to use a third device as a packet sniffer and check which packets are actually going over the air. Please see:

Hi Marie,

1) It was the central device. It directly entered GAP_LINK_PARAM_UPDATE_EVENT without entering GAP_UPDATE_LINK_PARAM_REQ_EVENT.

Hi Marie,

Now, I can enter GAP_UPDATE_LINK_PARAM_REQ_EVENT.

But I replied 'reject and yet I couldn't enter GAP_LINK_PARAM_UPDATE_REJECT_EVENT.

Could you please tell me where to make modifications?

Katherine

Hi Marie,

Are there any updates on my issue?

Katherine
