RE: pc-ble-driver-py max connection count

Hi, your suggestion works with minor changes.I was unable to find BLEConfigGap in ble_driver.py, but found BLEConfigGapRoleCount. The following code worked for me to increase central connection count to 8:

cfg = BLEConfigGapRoleCount()
cfg.central_role_count = 8 #8 central connections
cfg.periph_role_count = 0
cfg.central_sec_count = 0
self.adapter.driver.ble_cfg_set(BLEConfig.role_count, cfg)

Hi,

There are role count parameters in addition to the conn_cfg.conn_count parameter. Default value for central_role_count is 3, so if you need more than three connections as central, you should set the BLEConfigGap setting as well:

    cfg = BLEConfigGap()
    cfg.central_role_count = 4
    cfg.periph_role_count = 0
    cfg.central_sec_count = 1
    ble_tester.driver.ble_cfg_set(BLEConfig.role_count, cfg)

For details on the above parameters you can have a look at ble_gap_cfg_role_count_t in the SoftDevice API documentation.
