Need support for tuning the WiFi/BT for 1DX (brcm43430)

[JeDi_3998066]

Hello all,

We are currently using the 1DX Combo from Murata (brcm43430). We have some troubles with understanding / tuning the NVRAM params to get the best coexistence between BT and WiFi.

Brief description: if we change the btc_params8, btc_params1 and btc_params10 we get either great WiFi range / power / speed or BT A2DP cuts. We don't really understand what we are changing and we couldn't find any information about this.

Can someone help us from Cypress (MichaelF_56 or Murata (ToIn_1742091​) for paid support ?

If not, does someone know a 3rd party that knows this chip and can help with this ?

Thank you,

Jean

Hi,

Could you please check with the module vendor on tweaking the coex parameters(btc_params8, btc_params1 and btc_params10)?

Hello VinayakS_26​,

Thank you for this. Would you have any idea how to get documentation on this ?

We are trying currently to get support from Murata.

Thank you,

Hi Jean,

Currently there is no documentation available publicly for bt coex parameters.
