Probleme in the use of bt_gatt_subscribe in Bluetooth Shell sample

[Piwy]

Hi,

I use NCS 2.0.0 with 2 nrf52840, one peripheral with manny notification and one with Bletooth Shell sample.

I can see all notification of the peripheral with my Phone by with cmd gatt subscribe of Bluetooth shell command i can receive juste one notification, i don't know how to have more notifications, can you help me with that ?

For the first subscribe the subscribe_params.value_handle =0 but for another subscribe it's always another value , i add this observation but i don't know if it can help. And i have also print Subscribe failed with err = -120

Kind regards,

Pierre-Yves

Hi

I'm not sure I understand your problem here exactly. Can you explain what sample specifically you're using here? Is it the Bluetooth NUS Shell sample or one of the Zephyr tests located in ...\NCS_version\zephyr\tests\bluetooth\mesh_shell or ...\NCS_version\zephyr\tests\bluetooth\shell?

Error code -120 points to the subscribe is already in use. Can you show me a snippet of code on how you add these further subscriptions in your application?

Best regards,

Simon

Hello,

The sample that i am using is ...\NCS_version\zephyr\tests\bluetooth\shell?

I found why i couldn't subscribe to more notify, the cmd_subscribe from gatt.c don't permit more than one subscribe at a time (because there is only one subscribe_param....I created an other function to do subscribe and unsub for more notifications

In the old SDK NRF5 i could saw error code but i admit that in NCS i don't found where i can see error code, could you explain me were i can found error code like -120 ?
